Maxim’s MAX4655–MAX4658 are medium-voltage CMOS analog switches with low on-resistance of 10Ω max, specifically designed to handle large switch cur- rents. With a switch capability of up to 400mA peak cur- rent and 300mA continuous current (MAX4655/ MAX4656), and up to 300mA peak current and 150mA continuous current (MAX4657/MAX4658), these parts can switch loads as low as 25Ω. They can replace reed relays with a million times the speed and virtually unlim- ited number of lifetime cycles. Normal power consump- tion is only 3mW, whether the switch is on or off. These parts are TTL/CMOS compatible and will switch any voltage within its power-supply range. These are SPST (single-pole/single-throw) switches. The MAX4655/MAX4657 are normally closed (NC), while the MAX4656/MAX4658 are normally open (NO). The difference between the MAX4655/MAX4656 and the MAX4657/MAX4658 is in the power dissipation of their packages. Refer to the Absolute Maximum Ratings and the Electrical Characteristics. The MAX4655–MAX4658 power-supply range is from ±4.5V to ±20V for dual-supply operation and +9V to +40V for single-supply operation. These switches can operate from any combination of supplies, within a 40V V+ to V- range. They conduct equally well in either direc- tion and can handle rail-to-rail analog signals. The off- leakage current is only 1nA max at TA = +25°C. They are available in 8-pin µMAX®, TDFN, and SO packages, with exposed paddle options for high-power application

The MAX4533 is a quad, single-pole/double-throw (SPDT), fault-protected analog switch that is pin-compatible with the industry-standard MAX333 and MAX333A. It features fault-protected inputs and Rail-to-Rail® signal handling. The normally open (NO_ ) and normally closed (NC_ ) terminals are protected from overvoltage faults up to ±25V with power on and up to ±40V with power off. During a fault condition, NO_ and NC_ become high impedance with only nanoamperes of leakage current flowing to the source. In addition, the output (COM_) clamps to the appropriate polarity supply rail and provides up to ±10mA of load current. This ensures unambiguous rail-to-rail outputs when a fault occurs. The MAX4533 operates from dual ±4.5V to ±18V power supplies or a single +9V to +36V supply. All digital inputs have +0.8V and +2.4V logic thresholds, ensuring both TTL and CMOS logic compatibility when using ±15V supplies or a +12V supply. On-resistance is 175Ω max and is matched between switches to 10Ω max. The off- leakage current is only 0.5nA at TA = +25°C and 10nA at TA = +85°C. Applications include redundant/backup systems, portable instruments, test equipment, data-acquisition, communications systems, industrial and process control, and avionics systems.

In the 2:1 multiplexer mode, the output buffers for the HSYNC/VSYNC inputs are disabled, allowing bidirectional signaling. In both modes, DDC signals are voltage-clamped to an external voltage to provide level translation and protection. MAX4885 has a 5µA shutdown mode and is ESD protected to ±8kV Human Body Model (HBM) on externally routed pins. MAX4885 is specified over the extended (-40°C to +85°C) temperature range and is available in the 32-pin, 5mm x 5mm TQFN package.
