The PS398, an 8-channel single-ended mux, selects one of eight inputs to a common output as determined by a 3-bit address A0-A2. An EN (enable) pin when low disables all switches, use- ful when stacking several devices. The PS399 is a 4-channel differential multiplexer. It selects one of four differential inputs to a common differential output as determined by a 2-bit address A0, A1. An EN pin may be driven low to disable all switches. These multiplexers operate with dual supplies from +3V to +8V. Single-supply operation is possible from +3V to +15V. With +5V power supplies, the PS398/PS399 guarantee <100-ohm on-resistance . On-Resistance matching between channels is within 6-ohm. On-Resistance flatness is less than 11-ohm over the speci- fied signal range. Each switch conducts current equally well in either direction when on. In the off state each switch blocks voltages up to the power- supply rails. Both devices guarantee low leakage currents (<2.5nA at +85oC) and fast switching speeds (tTRANS <250ns). Break-before-make switching action protects against momentary crosstalk between channels.
