Monolithic CMOS Analog Multiplexers
General DescriptionFeatures
Maxim’s DG508A and DG509A are monolithic CMOS
oImproved Second Source
analog multiplexers (muxes): the DG508A is a single
8-channel (1-of-8) mux, and the DG509A is a differential
oOperate from ±4.5V to ±18V Supplies
4-channel (2-of-8) mux.
oSymmetrical, Bidirectional Operation
Both devices guarantee break-before-make switching.
oLogic and Enable Inputs, TTL and
Maxim guarantees these muxes will not latch up if the
CMOS Compatible
power supplies are turned off with the input signals still
oLatchup-Proof Construction
present. Maxim also guarantees continuous operation
when these devices are powered by supplies ranging
oMonolithic, Low-Power CMOS Design
from ±4.5V to ±18V.
Ordering Information
The DG508A/DG509A are plug-in upgrades for the indus-
try-standard DG08A/DG509A, respectively. Maxim’s parts
PARTTEMP RANGEPIN-PACKAGE
have lower on-resistance, faster enable switching times,
DG508ACJ0°C to +70°C16 Plastic DIP
and significantly lower leakage currents. The DG508A/
DG508ACWE0°C to +70°C16 Wide SO
DG509A also consume significantly lower power, making
DG508AC/D0°C to +70°CDice*
them ideal for portable equipment.
