74ALS253 - Dual 4-input multiplexer

General 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.

Key Features

  • 3-State outputs for bus interface and multiplex operation.
  • Common select inputs.
  • Separate output enable inputs.
