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.
