General Description

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 400

Ω max

and is matched between channels to 10

Ω max. All digi-

tal inputs have TTL logic thresholds, ensuring

TTL/CMOS-logic compatibility when using a single

+12V or dual ±15V supplies.
