DG508A/DG509A 19-0028 Rev 4 5/10 Monolithic CMOS Analog Multiplexers General Description Features Maxims DG508A and DG509A are monolithic CMOS Improved Second Source analog multiplexers (muxes): the DG508A is a single Operate from 4.5V to 18V Supplies 8-channel (1-of-8) mux, and the DG509A is a differen- tial 4-channel (2-of-8) mux. Symmetrical, Bidirectional Operation Both devices guarantee break-before-make switching. Logic and Enable Inputs, TTL and Maxim guarantees these muxes will not latch up if the CMOS Compatible power supplies are turned off with the input signals still present. Maxim also guarantees continuous operation Latchup-Proof Construction when these devices are powered by supplies ranging Monolithic, Low-Power CMOS Design from 4.5V to 18V. The DG508A/DG509A are plug-in upgrades for the Ordering Information industry-standard DG508A/DG509A, respectively. Maxims parts have faster enable switching times and PART TEMP RANGE PIN-PACKAGE significantly lower leakage currents. The DG508A/ DG508ACJ 0C to +70C 16 Plastic DIP DG509A also consume significantly lower power, mak- DG508ACWE 0C to +70C 16 Wide SO ing them ideal for portable equipment.

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. ELECTRICAL CHARACTERISTICS (V+ = 15V, V- = -15V, V = 0V, T = +25C, unless otherwise noted.)
