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
