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. 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. Fig.1 Functional diagram.
