74ALS253 Description
The 74ALS253 has two identical 4-input multiplexers with 3-State outputs which select 2 bits from four sources by using mon 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 implementation of 2-pole, 4-position switch being determined by the logic levels supplied to the mon...
