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. • Low Power Consumption 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. • Break-Before-Make Switching The DG508A is pinout compatible with the industry standard devices. • TTL and CMOS-Compatible Address and Enable Inputs • 44V Maximum Power Supply Rating • High Latch-Up Immunity • Alternate Source • Pb-free Available Applications • Data Acquisition Systems • Communication Systems • Signal Multiplexing/Demultiplexing • Audio Signal Multiplexing Ordering Information PART NUMBER TEMP.
