Quadruple 2-input multiplexer

HEF4019B

MSI

DESCRIPTION

The HEF4019B provides four multiplexing circuits with

common select inputs (SA, SB); each circuit contains two

inputs (An, Bn) and one output (On). It may be used to

select four bits of information from one of two sources.

The A inputs are selected when SA is HIGH, the B inputs

when SB is HIGH. When SA and SB are HIGH, output (On)

is the logical OR of the An and Bn inputs (On = An + Bn).

When SA and SB are LOW, output (On) is LOW

independent of the multiplexer inputs.
