This file introduces the MAX4514/MAX4515, which are single-pole/single-throw (SPST), CMOS, low-voltage, single-supply analog switches with very low switch on-resistance. MAX4514 is normally open (NO). MAX4515 is nor- mally 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 cur- rent maximum is only 1nA at +25°C or 20nA at +85°C. All digital inputs have 0.8V to 2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when using a +5V supply. For pin-compatible parts for use with dual supplies, see the MAX4516/MAX4517.

The MAX4613 is a low-voltage switch from Texas Instruments, with four channels, fast switching speed, low switch resistance, low leakage current, strong anti-static ability, and is widely used in various electronic products.

MAX4530/MAX4531/MAX4532 are low-voltage, CMOS analog ICs configured as an 8-channel multiplexer (mux) (MAX4530), two 4-channel muxes (MAX4531), and three single-pole/double-throw switches (MAX4532). These devices are pin compatible with the industry-standard 74HC4351/74HC4352/74HC4353. All devices have two complementary switch-enable inputs and address latching. The MAX4530/MAX4531/MAX4532 operate from a sin- gle supply of +2V to +12V, or from dual supplies of ±2V to ±6V. On-resistance (150Ω max) is matched between switches to 8Ω max. Each switch can handle rail-to-rail analog signals. Off-leakage current is only 1nA at TA = +25°C and 50nA at TA = +85°C. All digital inputs have 0.8V and 2.4V logic thresholds, ensuring both TTL- and CMOS-logic compatibility when using ±5V or a single +5V supply.

The document introduces the characteristics and functions of the MAX4536/MAX4537/MAX4538 series of low-voltage quad single-pole/single-throw (SPST) switches, including their application scenarios, operating voltage, switch resistance, leakage current, etc.

The MAX4551/MAX4552/MAX4553 are quad, low-volt- age, single-pole/single-throw (SPST) analog switches. Each switch is protected against ±15kV electrostatic discharge (ESD) shocks, without latchup or damage. On-resistance (100Ω max) is matched between switch- es to 4Ω max, and is flat (8Ω max) over the specified signal range. Each switch can handle Rail-to-Rail® ana- log signals. The off-leakage current is only 1nA at +25°C and 10nA at +85°C. The MAX4551 has four normally closed (NC) switches, and the MAX4552 has four normally open (NO) switch- es. The MAX4553 has two NC and two NO switches. These CMOS switches can operate with dual power supplies ranging from ±2V to ±6V or a single supply between +2V and +12V. They are fully specified for sin- gle +2.7V operation. All digital inputs have +0.8V and +2.4V logic thresh- olds, ensuring TTL/CMOS-logic compatibility when using ±5V or a single +5V supply.

MAX4610/MAX4611/MAX4612 Low-Voltage, Quad, SPST CMOS Analog Switches

The MAX16999 linear regulator operates from a 2.5V to 5.5V input voltage and delivers 100mA continuous load current with a low quiescent current typically around 13µA. The output voltage is preset to internally trimmed voltages in the 0.5V to 3.3V range (see the Selector Guide). An active-low, open-drain reset output remains low for a programmable timeout delay after the output voltage reaches regulation. The reset timeout is pro- grammed by an external capacitor connected to CRES. This device also features logic-controlled shutdown, and short-circuit and thermal-overload protection. The typical applications are multimedia, telematics, and motor control microcontrollers (µCs) with always-on requirements. The MAX16999 is used as a parallel, low- quiescent supply to power the core or interrupt section of µCs during sleep mode. It can also be used to sup- ply a timer or memory during µC shutoff. The adjustable POR delay assists with power-supply sequencing. Applications include industrial SDRAM power supplies, keep-alive timers, and handheld/portable devices.

MAX4580/MAX4590/MAX4600 dual analog switches feature low on-resistance (1.25Ω max).

The MAX4511/MAX4512/MAX4513 are quad, single- pole/single-throw (SPST), fault-protected analog switch- es.

The DG202/DG212 are normally open, quad single-pole single-throw (SPST) analog switches. These CMOS switches can be continuously operated with power supplies ranging from ±4.5V to ±18V. Maxim guarantees that these switches will not latch up if the power supplies are disconnected with input signals still connected. The DG202/DG212 are similar to the DG201/DG211 except for inverted control inputs. All devices have guaranteed break-before-make switching, as well as essentially constant on-resistance over the analog signal range. All switches conduct current in either direction and add no offset to the output signal. Compared to the original manufacturer’s products, Maxim’s DG202/DG212 consume very little power, making them better suited for portable applications. Maxim has also eliminated the need for the third logic power supply (VL) that is required for the operation of the original manufacturer’s DG212 without sacrificing compatibility.

Maxim’s DG528/DG529 are monolithic, 8-channel, CMOS multiplexers with on-board address and control latches that simplify design and reduce board space in microprocessor-based applications. The DG528 is a single-ended, 1-of-8 multiplexer, while the DG529 is a differential, 2-of-8 multiplexer. These devices can operate as multiplexers or demultiplexers. The DG528/DG529 have break-before-make switching to prevent momentary shorting of the input signals. Each device operates with dual supplies (±4.5V to ±20V) or a single supply (+5V to +30V). All logic inputs are TTL and CMOS compatible. The Maxim DG528/DG529 are pin and electrically compatible with the industry-standard DG528/DG529.

The DG506A/DG507A are monolithic CMOS analog multiplexers from Maxim. The DG506A is a single 16-channel (1 of 16) multiplexer and the DG507A is a differential 8-chan- nel (2 of 16) multiplexer. Both devices feature break-before-make switching. Maxim guarantees that these multiplexers will not latch- up if the power supplies are turned off with the input signals still present as long as absolute maximum ratings are not violated. The multiplexers operate over a wide range of power supplies from Q4.5V to Q18V. Compared to the original manufacturer’s devices, Maxim’s DG506A/DG507A consume significantly less power, making them ideal for portable equipment.

This datasheet provides the specifications of Maxim's DG441/DG442 analog switches. This switch has low on-resistance, low power consumption, and can withstand high voltage electrostatic discharge.
