MC54HC158 - Quad 2-Input Data Selector/Multiplexer

Description

INPUTS A0

A3 (Pins 2,5,11,14) Nibble A inputs.

The data present on these pins is transferred to the outputs when the Select input is at a low level and the Output Enable input is at a low level.

The data is presented to the outputs in inverted form for the HC158.

B3 (Pins 3,6,10,

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Quad 2-Input Data Selector/Multiplexer High–Performance Silicon–Gate CMOS The MC54/74HC158 is identical in pinout to the LS158. The device inputs are compatible with Standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. These devices route 2 nibbles (A or B) to a single port (Y) as determined by the Select input. The data is presented at the outputs in inverted form for the HC158. A high level on the Output Enable input sets all four Y outputs to a high level for the HC158.
