_______________General Description

The MAX354/MAX355 fault-protected multiplexers

(muxes) use a series N-channel, P-channel, N-channel

structure that protects the devices from overvoltage up

to 40V beyond the supply rails during power-up, power-

down, and fault conditions. The MAX354/MAX355 also

protect sensitive circuit components against voltages

near or beyond the normal supplies.

The MAX354 single 8-channel mux and the MAX355

dual 4-channel mux protect analog signals while oper-

ating from a single 4.5V to 36V supply or ±4.5V to ±18V

dual supplies. These muxes have 350

Ω on-resistance

and can be used for demultiplexing as well as multi-

plexing. Input leakage current is less than 0.5nA at

+25°C and less than 5nA at +85°C.

All digital inputs have 0.8V and 2.4V logic thresholds,

ensuring both TTL and CMOS logic compatibility with-

out pull-up resistors. Break-before-make operation is

guaranteed and power consumption is less than

1.5mW.
