Description of 74253 Data Selectors/Mux 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 directly with data lines of bus-organized systems. With all but one of the common outputs disabled (at a high impedance state), the low impedance of the single enabled output will drive the bus line to a HIGH or LOW logic level. Features 3-STATE version of DM74LS153 with same pinout Schottky-diode-clamped transistors Permit multiplexing from N-lines to one line Performs parallel-to-serial conversion Strobe/output control High fanout totem-pole outputs Typical propagation delay Data to output 12 nsSelect to output 21 ns Typical power dissipation 35 mW
