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.

Note 1: COM_, EN, and A_ pins are not fault protected. Signals on COM_, EN, or A_ exceeding V+ or V- are clamped by internal
diodes. Limit forward diode current to maximum current rating.
Note 2: NO_ pins are fault-protected. Signals on NO_ exceeding -25V to +25V may damage the device during power-on conditions.
When the power is off the maximum voltage range is -40V to +40V.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
ELECTRICAL CHARACTERISTICS—Dual Supplies
(V+ = +15V, V- = -15V, VA_H = VENH = 2.4V, VA_L = VENL = 0.8V, TA = TMIN to TMAX, unless otherwise noted. Typical values are at
TA = +25°C.) (Note 3)
