Description

The PS398/PS399 are improved high precision analog multiplexers.

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 +85

and fast switching speeds (t

switching action protects against momentary crosstalk between

channels.
