Maxim DG509AC/D Monolithic cmos analog multiplexer Datasheet

19-0028; Rev 4; 5/10
Monolithic CMOS Analog Multiplexers
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
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, making them ideal for portable equipment.
Applications
Features
♦ Improved Second Source
♦ Operate from ±4.5V to ±18V Supplies
♦ Symmetrical, Bidirectional Operation
♦ Logic and Enable Inputs, TTL and
CMOS Compatible
♦ Latchup-Proof Construction
♦ Monolithic, Low-Power CMOS Design

Note 1: Signals on S_ or D_ exceeding V+ or V- are clamped by internal diodes. Limit forward-diode current to maximum current ratings
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.
