Monolithic CMOS Analog Multiplexers
General Description
Features
ꢀ Improved Second Source
Maxim’s DG508A and DG509A are monolithic CMOS
analog multiplexers (muxes): the DG508A is a single
8-channel (1-of-8) mux, and the DG509A is a differential
4-channel (2-of-8) mux.
ꢀ Operate from ±±4.5 to ±ꢀꢁ5 Suppꢂꢃei
ꢀ Symmetrꢃcaꢂ, Bꢃdꢃrectꢃonaꢂ Operatꢃon
ꢀ Logꢃc and Enabꢂe Inputi, TTL and
Both devices guarantee break-before-make switching.
Maxim guarantees these muxes will not latch up if the
power supplies are turned off with the input signals still
present. Maxim also guarantees continuous operation
when these devices are powered by supplies ranging
from 4.5ꢀ to 18ꢀ.

Ordering Information
The DG508A/DG509A are plug-in upgrades for the indus-
try-standard DG08A/DG509A, respectively. Maxim’s parts
have lower on-resistance, faster enable switching times,
and significantly lower leakage currents. The DG508A/
DG509A also consume significantly lower power, making
them ideal for portable equipment.
