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 <100Ohm
on-resistance. On-resistance matching between channels is within
6Ohm. On-resistance flatness is less than 11Ohm 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
o
C)
and fast switching speeds (t
TRANS
<250ns). Break-before-make
switching action protects against momentary crosstalk between
channels.
