HEF4019B

Application

An example of an application for the HEF4019B is:
· True/complement selection.


Pinout




Description

The HEF4019B provides four multiplexing circuits with common select inputs (SA, SB); each HEF4019B 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.
