NXP Semiconductors HEF4019B

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. When SA and SB are HIGH, output (On) is the logical OR of the An and Bn inputs (On = An + Bn).

DESCRIPTION

HEF4019B MSI The A inputs are selected when SA is HIGH, the B inputs when SB is HIGH. When SA and SB are LOW, output (On) is LOW independent of the multiplexer inputs. Fig.1 Functional diagram.
