♦ Low-Power, Monolithic CMOS Design
♦ On-Board Address Latches
Ma xim’s DG528/DG529 a re monolithic , 8-c ha nne l,
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.
♦ Break-Before-Make Input Switches
♦ TTL and CMOS Logic Compatible
♦ Microprocessor-Bus Compatible
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
a re TTL a nd CMOS c omp a tib le . The Ma xim
DG528/DG529 are pin and electrically compatible with
the industry-standard DG528/DG529.
