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.
