The is a CMOS Monolithic 8-Channel Analog Multiplexer, which can also be used as a demultiplexer. An enable input is provided. When the enable input is high, a channel is selected by the address inputs, and when low, all channels are off. A channel in the ON state conducts current equally well in both directions. In the OFF state each channel blocks voltages up to the supply rails. The address inputs and the enable input are TTL and CMOS compatible over the full specified operating temperature range. The DG508A is pinout compatible with the industry standard devices.

Features

Low Power Consumption TTL and CMOS-Compatible Address and Enable Inputs 44V Maximum Power Supply Rating High Latch-Up Immunity Break-Before-Make Switching Alternate Source

Applications

Data Acquisition Systems Communication Systems Signal Multiplexing/Demultiplexing Audio Signal Multiplexing
