Package Information

The MAX4631/MAX4632/MAX4633 high-voltage, dual analog switches are pin compatible with the industry-standard DG401/DG403/DG405. They upgrade the existing devices with fault-protected inputs and Rail-to-Rail® signal handling capabilities.

MAX4607/MAX4608/MAX4609 are dual analog switches featuring 2.5Ω max low on-resistance. On-resistance is matched between switches to 0.5Ω max and is flat (0.5Ω max) over the specified signal range. Each switch can handle rail-to-rail analog signals. The off-leakage current is only 2.5nA max at +85°C. These analog switches are ideal in low-distortion applications and are the preferred solution over mechanical relays in automatic test equip- ment or applications where current switching is required. They have low power requirements, require less board space, and are more reliable than mechanical relays. The MAX4607 has two normally closed (NC) switches, the MAX4608 has two normally open (NO) switches, and the MAX4609 has one NC and one NO switch. These switches operate from a single supply of +4.5V to +36V or from dual supplies of ±4.5V to ±20V. All digital inputs have +0.8V and +2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when using dual ±15V or a single +12V supply.

The MAX4539/MAX4540 low-voltage, CMOS 8-channel (MAX4539) and dual 4-channel (MAX4540) multiplexers are ideal for precision ADC calibration and system self-monitoring applications. These calibration multiplexers (cal-muxes) have precision resistor-dividers to generate accurate voltage ratios from an input reference voltage. The reference ratios include 15/4096 and 4081/4096 of the external reference voltage, accurate to 15 bits, and 1/2V+ and 5/8(V+ - V-), accurate to 8 bits. The external reference voltage as well as ground can also be switched to the output. The MAX4539/MAX4540 have enable inputs and address latching. All digital inputs have 0.8V and 2.4V logic thresholds, ensuring both TTL- and CMOS-logic compatibility when using a ±5V or a single +5V supply. Protection diodes at all inputs provide an ESD rating >2kV. The MAX4539/MAX4540 operate from a single +2.7V to +12V supply, or from dual supplies of ±2.7V to ±6V. On-resistance (100Ω max) is matched between switches to 6Ω max. Each switch can handle Rail-to-Rail® analog signals. The off leakage current is 0.1nA at TA = +25°C and 2nA at TA = +85°C. The MAX4539/MAX4540 are available in small 20-pin DIP, SO, and SSOP packages.

MAX4581/MAX4582/MAX4583 are low-voltage CMOS analog ICs configured as an 8-channel multiplexer (MAX4581), two 4-channel multiplexers (MAX4582), and three single-pole/double-throw (SPDT) switches (MAX4583). These CMOS devices can operate continuously with ±2V to ±6V dual power supplies or a +2V to +12V sin- gle supply. Each switch can handle rail-to-rail analog signals. The off-leakage current is only 1nA at +25°C or 5nA at +85°C. All digital inputs have 0.8V to 2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when using a single +5V or dual ±5V supplies.

MAX4510/MAX4520 is a single-pole single-throw (SPST) fault-protected analog switch with a fault-protected input and Rail-to-Rail® signal-handling capability. The switch's normally open (NO) and normally closed (NC) terminals are protected from overvoltage faults up to 36V during power-on and 44V with power off. During a fault condi- tion, the switch input terminal (NO or NC) becomes an open circuit; only nanoamperes of leakage current flow from the fault source, and the switch output (COM) fur- nishes up to 13mA of the appropriate polarity supply voltage to the load. This ensures unambiguous rail-to-rail outputs when a fault begins and ends. On-resistance is 160Ω max. The off-leakage current is only 0.5nA at +25°C and 10nA at +85°C. The MAX4510 is a normally closed switch, while the MAX4520 is a normally open switch. These CMOS switches operate with dual power supplies ranging from ±4.5V to ±20V or a single supply between +9V and +36V. The digital input has +0.8V and +2.4V logic thresholds, ensuring both TTL- and CMOS-logic compatibility when using ±15V or a single +12V supply. The MAX4510/ MAX4520 are available in 6-pin SOT23 and 8-pin µMAX packages. Applications include Data Acquisition, Industrial and Process-Control Systems, Avionics, ATE Equipment, Redundant/Backup Systems. Features include ±40V Fault Protection with Power Off, ±36V Fault Protection with ±15V Supplies, Switch is Off with Power Removed, Rail-to-Rail Signal Handling, 160Ω max Signal Paths with ±15V Supplies.

Maxim's redesigned DG411/DG412/DG413 analog switches now feature low on-resistance matching between switches (3Ω max) and guaranteed on-resistance flatness over the signal range (Δ4Ω max). These low on-resistance switches conduct equally well in either direction. They guarantee low charge injection, low power consumption, and an ESD tolerance of 2000V minimum per Method 3015.7. The new design offers lower off-leakage current over temperature (less than 5nA at +85°C). The DG411/DG412/DG413 are quad, single-pole/single-throw (SPST) analog switches. The DG411 is normally closed (NC), and the DG412 is normally open (NO). The DG413 has two NC switches and two NO switches. Switching times are less than 150ns max for tON and less than 100ns max for tOFF. These devices operate from a single +10V to +30V supply, or bipolar ±4.5V to ±20V supplies. Maxim's improved DG411/DG412/DG413 are fabricated with a 44V silicon-gate process.

The MAX4501/MAX4502 are single-pole/single-throw (SPST), low-voltage, single-supply, CMOS analog switches. The MAX4501 is normally open (NO). The MAX4502 is normally closed (NC). These CMOS switches can operate continuously with a single supply between +2V and +12V. Each switch can handle Rail-to-Rail® analog signals. The off-leakage current is only 1nA at +25°C or 10nA at +85°C. The digital input has 0.8V and 2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when using a single +5V supply.

DG408/DG409 is a CMOS analog multiplexer with guaranteed 8Ω channel matching and 9Ω flatness. These low-on-resistance multiplexers (100Ω max) conduct equally well in either direction and feature guaranteed low charge injection of 15pC max. In addition, these new multiplexers offer low input off-leakage current over temperature - less than 5nA at +85°C. DG408 is a 1-of-8 multiplexer/demultiplexer and DG409 is a dual 4-channel multiplexer/demultiplexer. Both multiplexers operate with a single +5V to +30V supply and with ±5V to ±20V dual supplies. ESD protection is guaranteed to be greater than 2000V per Method 3015.7 of MIL-STD-883. These improved multiplexers are pin-compatible plug-in upgrades for the industry standard DG408 and DG409.

The MAX5943 is a fully integrated power-management IC for FireWire applications. This device controls two external power n-channel MOSFETs to regulate current from the input power supply to the load and performs low-voltage-drop, power-supply ORing. The MAX5943 operates over a 7.5V to 37V input range and provides inrush and output current limit in addition to a diode ORing function suitable for FireWire applications. The MAX5943 allows the safe insertion and removal of FireWire peripherals into a live FireWire port by providing inrush current control and an output current-limiting function. The ORing feature provides a very efficient way to protect the FireWire port when connected to another FireWire peripheral that sources a higher voltage. By turning off both external MOSFETs, the MAX5943 provides a true bidirectional load disconnect. A low-current shutdown mode disables the MAX5943, resulting in less than 10µA supply current. A pin-selectable input allows latched or autoretry fault management after a fault. The MAX5943A features a current-limit function that actively limits the current drawn by the load with a programmable timeout. The MAX5943B–MAX5943E do not actively limit the load current but provide a circuit-breaker function. See the Selector Guide for the default and programmable circuit-breaker timeouts. The MAX5943 operates over the -40°C to +85°C extended temperature range and is available in a 16-pin QSOP package.

MAX4680/MAX4690/MAX4700 dual analog switches feature low on-resistance of 1.25Ω max. On-resistance is matched between switches to 0.3Ω max and is flat (0.3Ω max) over the specified signal range. Each switch can handle Rail-to-Rail® analog signals. Off-leakage current is only 5nA max at +85°C. These analog switches are ideal in low-distortion applications and are the preferred solution over mechanical relays in automatic test equipment or applications where current switching is required. They have low power requirements, require less board space, and are more reliable than mechanical relays. The MAX4680 has two NC (normally closed) switches, and the MAX4690 has two NO (normally open) switch- es. The MAX4700 has one NC and one NO switch and features guaranteed break-before-make switching. These devices operate from a +4.5V to +36V single supply or from ±4.5V to ±20V dual supplies. A separate logic supply pin guarantees TTL/CMOS-logic compatibility while operating across the entire supply voltage range.

The MAX4661/MAX4662/MAX4663 are quad analog switches with low on-resistance and flat switching characteristics. They are suitable for low-distortion applications and can replace mechanical relays. These switches have lower power requirements, use less board space, and are more reliable than mechanical relays.

MAX4667/MAX4668/MAX4669 are MAXIM's three dual analog switches, with low on-resistance (2.5 ohms max), on-resistance matching (0.5 ohms max) and voltage range consistency (0.5 ohms max). Each switch can handle Rail-to-Rail® analog signals. The switch-off current is only 5nA max at +85°C. These analog switches are ideal for low distortion applications and are the preferred solution over mechanical relays in automatic test equipment or applications where current switching is required. They have low power requirements, occupy less board space and are more reliable than mechanical relays. MAX4667 has two normally closed (NC) switches, MAX4668 has two normally open (NO) switches and MAX4669 has one NC and one NO switch to ensure break-before-make operation. These switches can operate from a +4.5V to +36V single supply or from ±4.5V to ±20V dual supplies. All digital inputs have +0.8V and +2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when using ±15V supplies or a single +12V supply.
