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.
