It may be used to select four bits of information from one of two sources. HEF4019B MSI 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.
