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 differential

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 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.

ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS

(V+ = 15V, V- = -15V, GND = OV, T

= +25°C, unless otherwise noted.)

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional

operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to

absolute maximum rating conditions for extended periods may affect device reliability.
