MC54F353 Datasheet DUAL 4-INPUT MULTIPLEXER

Manufacturer: Motorola Semiconductor (now NXP Semiconductors)

General Description

The MC54/74F353 contains two identical 4-input multiplexers with 3-state outputs.

They select two bits from four sources selected by common Select inputs (S0, S1).The 4-input multiplexers have individual Output enable (OEa, OEb) inputs which, when HIGH, force the outputs to a high impedance (high Z) state.

The logic equations for the outputs are shown below: Za=OEa • (I0a • S1 • S0 +I1a • S1 • S0 + I2a • S1 • S0 + I3a • S1 • S0) Zb=OEb• (I0b • S1 • S0 + I1b • S1

Overview

DUAL 4-INPUT MULTIPLEXER WITH 3-STATE OUTPUTS The MC54/74F353 is a dual 4-input multiplexer with 3-state outputs.

It can select two bits of data from four sources using common Select inputs.

The outputs may be individually switched to a high impedance state with a HIGH on the respective Output Enable (OE) inputs, allowing the outputs to interface directly with bus-oriented systems.
