DG528, DG529
Vishay Siliconix
Latchable Single 8-Ch/Differential 4-Ch Analog Multiplexers
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 applica-
tions. 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.
