74S253
Description
Each of these Schottky-clamped data selectors/multiplexers contains inverters and drivers to supply fully plementary, 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 directly with data lines of bus-organized systems. With all but one of the mon outputs disabled (at a high impedance state), the low impedance of the single enable output will drive the bus line to a HIGH or LOW logic level.
Features 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 Strobe/output control s High fan-out totem-pole outputs s Typical propagation delay
From data to output 6 ns From select to output 12 ns s Typical power dissipation 275 m W
