74153: Dual 1-of-4 Data Selector

This package selects one of four inputs and provides the data on the selected input as its output. There are two separate 1-of-4 selectors with two separate outputs, but their addresses are common.

Inputs to the 1 Address and the 2 Address select the output connection for both sides simultaneously. Input data is not inverted and passed onto the output.

The Enable must be low to get an output. A high Enable drives the output low, independently of input data.

Note that both halves of this circuit have common address lines, although they have separate inputs, outputs, and enables.
