MAX354/MAX355 19-0389 Rev. 2 9/96 Fault-Protected Analog Multiplexers General Description Features The MAX354/MAX355 fault-protected multiplexers 350 Max On-Resistance (muxes) use a series N-channel, P-channel, N-channel Improved 2nd Source for MAX358/MAX359 and structure that protects the devices from overvoltage up DG458/DG459 to 40V beyond the supply rails during power-up, power- Pin Compatible with ADG508F/ADG509F down, and fault conditions. The MAX354/MAX355 also protect sensitive circuit components against voltages All Switches Off with Supplies Off near or beyond the normal supplies. On Switch Turns Off with Overvoltage The MAX354 single 8-channel mux and the MAX355 Output Clamps at 1.5V Below Supply Rails dual 4-channel mux protect analog signals while oper- 0.5nA Max Input Leakage at +25C (5nA at +85C) ating from a single 4.5V to 36V supply or 4.5V to 18V No Power-Up Sequencing Required dual supplies. These muxes have 350 on-resistance and can be used for demultiplexing as well as multi- TTL and CMOS-Logic Compatibility plexing. Input leakage current is less than 0.5nA at +25C and less than 5nA at +85C. Ordering Information All digital inputs have 0.8V and 2.4V logic thresholds, ensuring both TTL and CMOS logic compatibility with- PART TEMP. RANGE PIN-PACKAGE out pull-up resistors.
