      The MAX4534 (single 4-to-1) and MAX4535 (dual 2-to-1) fault-protected multiplexers operate with ±4.5V to ±20V dual supplies or a +9V to +36V single supply. The MAX4534 feature fault-protected inputs, Rail-to-Rail^® signal-handling capability, and overvoltage clamping at 150mV beyond the rails. Both parts feature ±40V over voltage protection with supplies off and ±25V protection with supplies on. On-resistance is 400? max and is matched between channels to 10? max. All digital inputs of MAX4534 have TTL logic thresholds, ensuring TTL/CMOS-logic compatibility when using a single +12V or dual ±15V supplies.
