Fault-Protected Analog Multiplexers
_______________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 鹵4.5V to 鹵18V
dual supplies. These muxes have 350鈩?on-resistance
and can be used for demultiplexing as well as multi-
plexing. Input leakage current is less than 0.5nA at
+25擄C and less than 5nA at +85擄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.
