general description the max14752/max14753 are 8-to-1 and dual 4-to-1 high-voltage analog multiplexers. both devices feature 60 (typ) on-resistance with 0.03 (typ) on-resistance flatness. these low on-resistance multiplexers conduct equally well in either direction. flexible logic levels for the channel-select interface are defined by the en input. the max14752 is a 8-to-1 multiplexer and max14753 is a dual 4-to-1 multiplexer. both devices operate with dual supplies of ?0v to ?6v, or a single supply of +20v to +72v. the max14752/max14753 are available in a 16-pin tssop package and are pin compatible with the indus- try-standard dg408/dg409. both the max14752/ max14753 are specified over the extended -40? to +85? operating temperature range. applications programmable-logic controllers environment control systems ate systems medical monitoring systems automotive features ? wide dual power-supply range ?6v (max) ? wide single power-supply range +72v (max) ? low on-resistance 60 (typ) ? r on flatness over common-mode voltage 0.03 (typ) ? low-input (20na) on-leakage current (max) ? en voltage defines logic level of s0, s1, and s2 ? low i dd supply current in disable mode 25?
