Description

Features, Applications

Maxim's DG508A and DG509A are monolithic CMOS analog multiplexers (muxes): the is a single 8-channel (1-of-8) mux, and the 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 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. Improved Second Source Operate from 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 or D_ exceeding 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.
