_______________General Description

Maxim’s DG528/DG529 are monolithic, 8-channel,

CMOS multiplexers with on-board address and control

latches that simplify design and reduce board space in

microprocessor-based applications. The DG528 is a

single-ended, 1-of-8 multiplexer, while the DG529 is a

differential, 2-of-8 multiplexer. These devices can oper-

ate as multiplexers or demultiplexers.

The DG528/DG529 have break-before-make switching

to prevent momentary shorting of the input signals.

Each device operates with dual supplies (±4.5V to

±20V) or a single supply (+5V to +30V). All logic inputs

are TTL and CMOS compatible. The Maxim

DG528/DG529 are pin and electrically compatible with

the industry-standard DG528/DG529.
