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.
