Overview

INTEGRATED CIRCUITS 74ALS253 Dual 4–input multiplexer (3–State) Product specification IC05 Data Handbook 1991 Feb 08 Philips Semiconductors Philips Semiconductors Product specification Dual 4-input multiplexer (3-State) 74ALS253 FEATURES • 3-State outputs for bus interface and multiplex operation • Common select inputs • Separate output enable inputs DESCRIPTION The 74ALS253 has two identical 4-input multiplexers with 3-State outputs which select 2 bits from four sources by using common select input (S0, S1).
When the individual output enable (OEa, OEb) inputs of the 4-input multiplexers are High, the outputs are forced to a High impedance (Z) state.
The 74ALS253 is the logic impleme...
