DM74S253 selector/multiplexer equivalent, dual 3-state 1-of-4 line data selector/multiplexer.
s 3-STATE version of S153 with same pin-out s Schottky-diode-clamped transistors s Permits multiplexing from N lines to 1 line s Performs parallel-T-serial conversion s S.
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.
