74S253 Dual 3-STATE 1-of-4 Line Data Selector/Multiplexer

Each of these Schottky-clamped data selectors/multiplexers contains inverters and drivers to supply fully complementary, on-chip, binary decoding data selection to the AND-OR gates. Separate output control inputs are provided for each of the two four-line sections. The 3-STATE outputs can interface .
