Fault-Protected, High-Voltage,
Single 4-to-1/Dual 2-to-1 Multiplexers
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 over-
voltage 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.
