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 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 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. o Improved Second Source o Operate from ±4.5V to ±18V Supplies o Symmetrical, Bidirectional Operation o Logic and Enable Inputs, TTL and CMOS Compatible o Latchup-Proof Construction o Monolithic, Low-Power CMOS Design

Note 1: Signals on S_, D_, or IN_ 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.

VS = input to off switch, VD = output due to VS. Note 4: Electrical characteristics (such as on-resistance) change when power supplies other than ±15V are used. Note 5: For designs requiring single 5V or dual ±5V operation, refer to Maxim's improved MAX338 and MAX339. Minimum operating voltage for DG508ADY and DG509ADY is ±9V.
