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

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

Ω max and is

matched between channels to 10

Ω max. All digital inputs

have TTL logic thresholds, ensuring TTL/CMOS-logic

compatibility when using a single +12V or dual ±15V

supplies.
