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. These multiplexers feature fault-protected inputs, rail-to-rail signal-handling capability, and overvoltage clamping at 150mV beyond the rails. Both parts feature ±40V overvoltage protection with supplies off and ±25V protection with supplies on. On-resistance is 400Ω max and is matched between channels to 10Ω max. All digital inputs have TTL logic thresholds, ensuring TTL/CMOS-logic compatibility when using a single +12V or dual ±15V supplies.
