DESCRIPTION

The DG528 is an 8-channel single-ended analog multiplexer

designed to connect one of eight inputs to a common output as

determined by a 3-bit binary address (A0, A1, A2). DG529, a

4-channel dual analog multiplexer, is designed to connect one

of four differential inputs to a common differential output as

determined by its 2-bit binary address (A0, A1) logic.

These analog multiplexers have on-chip address and control

latches

to

simplify

design

in

microprocessor

based

applications. Break-before-make switching action protects

against momentary shorting of the input signals. The

DG528/529 are built on the improved PLUS-40 CMOS

process. A buried layer prevents latchup.

The on chip TTL-compatible address latches simplify digital

interface design and reduce board space in data acquisition

systems, process controls, avionics, and ATE.
