8-Channel Latchable Multiplexers
_______________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.
