Product Summary
The 74HC253D is a high-speed Si-gate CMOS device and is pin compatible with low power Schottky TTL (LSTTL). It is specified in compliance with JEDEC standard no. 7A. The 74HC253D has two identical 4-input multiplexers with 3-state outputs which select two bits from four sources selected by common data select inputs (S0, S1). When the individual output enable (1OE, 2OE) inputs of the 4-input multiplexers are HIGH, the outputs are forced to the high impedance OFF-state. The "253" is the logic implementation of a 2-pole, 4-position switch, where the position of the switch is determined by the logic levels applied to S0 and S1. The applications of the 74HC253D include Data selectors, Data multiplexers.
