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.

Features
♦ 350Ω Max On-Resistance
♦ Improved 2nd Source for MAX358/MAX359 and
   DG458/DG459
♦ Pin Compatible with ADG508F/ADG509F
♦ All Switches Off with Supplies Off
♦ On Switch Turns Off with Overvoltage
♦ Output Clamps at 1.5V Below Supply Rails
♦ 0.5nA Max Input Leakage at +25°C (5nA at +85°C)
♦ No Power-Up Sequencing Required
♦ TTL and CMOS-Logic Compatibility
