Fault-Protected Analog Multiplexers
____________________________Features
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, powerdown, and fault conditions. The MAX354/MAX355 also
protect sensitive circuit components against voltages
near or beyond the normal supplies.
o 350Ω Max On-Resistance
o Improved 2nd Source for MAX358/MAX359 and
DG458/DG459
o Pin Compatible with ADG508F/ADG509F
o All Switches Off with Supplies Off
o On Switch Turns Off with Overvoltage
o Output Clamps at 1.5V Below Supply Rails
o 0.5nA Max Input Leakage at +25°C (5nA at +85°C)
o No Power-Up Sequencing Required
o TTL and CMOS-Logic Compatibility
The MAX354 single 8-channel mux and the MAX355
dual 4-channel mux protect analog signals while operating from a single 4.5V to 36V supply or ±4.5V to ±18V
dual supplies. These muxes have 350Ω on-resistance
and can be used for demultiplexing as well as multiplexing. 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 without pull-up resistors. Break-before-make operation is
guaranteed and power consumption is less than
1.5mW.
