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, the output (On) is the logical EXCLUSIVE-NOR of the An and Bn inputs (On = An Bn). HEF4519B MSI When SA and SB are LOW, the output (On) is LOW, independent of the multiplexer inputs (An and Bn). The HEF4519B cannot be used to multiplex analogue signals. The outputs utilize standard buffers for best performance. Fig.1 Functional diagram.
