MAX359CWE SO-16 2-of-8 multiplexer

Fault-Protected Analog Multiplexer

Maxim's MAX359 is a 4 channel differential (2 of 8) multiplexer with fault protection.

Using a series N-channel, P-channel, N-channel structure this multiplexe provides significantly improved fault protection.
If the power supplies to the Maxim fault-protected multiplexer are inadvertently turned off while input voltages are still applied, all channels in the multiplexer are turned off, and only a few nanoamperes of leakage current will flow into the inputs.
This protects not only the multiplexer, but also protects the sensors or signal sources which drive the multiplexer.


Features

* All switches off with power supplies off
* On channel turns off i overvoltage occurs
* Only nanoamperes of input current under all fault conditions
* Latchup-proof construction
* Operates from +/-4.5 to +/-18V supplies
* All digital inputs are TTL and CMOS compatible


Applications

* Data acquisition systems
* Industrial and process control systems
* Avionics test equipment
* Signal routing between systems
