HD74HC153 - Dual 4-to-1-line Data Selectors/Multiplexers

General Description

Information on the data inputs of each multiplexer is selected by the address on the A and B inputs, and is presented on the Y outputs.

Each multiplexer possesses a strobe input which enables it when taken to a low logic level.

Key Features

HD74HC153 Dual 4-to-1-line Data Selectors/Multiplexers Description Information on the data inputs of each multiplexer is selected by the address on the A and B inputs, and is presented on the Y outputs. Each multiplexer possesses a strobe input which enables it when taken to a low logic level. When a high logic level is applied to a strobe input, the output of its associated multiplexer is taken low.
