Monolithic CMOS Analog Multiplexers
General Description
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 differen-
tial 4-channel (2-of-8) mux.
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 ±4.5V to ±18V.
The DG508A/DG509A are plug-in upgrades for the
industry-standard DG508A/DG509A, respectively.
Maxim’s parts have faster enable switching times and
significantly lower leakage currents. The DG508A/
DG509A also consume significantly lower power, mak-
ing them ideal for portable equipment.
