Fault-Protected, High-Voltage,
Single 4-to-1/Dual 2-to-1 Multiplexers
General Description
Features
The MAX4534 (single 4-to-1) and MAX4535 (dual 2-to-
1) fault-protected multiplexers operate with 4ꢀ5ꢁ to
2ꢂꢁ dual supplies or a ꢃ+ꢁ to ꢃ3ꢄꢁ single supplꢅꢀ
These multiplexers feature fault-protected inputs, rail-
to-rail signal-handling capabilitꢅ, and overvoltage
clamping at 15ꢂmꢁ beꢅond the railsꢀ Both parts feature
4ꢂꢁ overvoltage protection with supplies off and 25ꢁ
protection with supplies onꢀ On-resistance is 4ꢂꢂΩ max
and is matched between channels to 1ꢂΩ maxꢀ All digi-
tal inputs have TTL logic thresholds, ensuring
TTL/CMOS-logic compatibilitꢅ when using a single
ꢃ12ꢁ or dual 15ꢁ suppliesꢀ
