Quadruple 2-input multiplexer

MSI
DESCRIPTION
The HEF4519B 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.
The ‘A’ inputs are selected when SAis HIGH, the ‘B’ inputs when SBis HIGH. When SAand SBare HIGH, the output (On) is the logical EXCLUSIVE-NOR of the Anand Bninputs (On= A
n
Bn).
When SAand SBare LOW, the output (On) is LOW, independent of the multiplexer inputs (Anand Bn).
The HEF4519B cannot be used to multiplex analogue signals. The outputs utilize standard buffers for best performance.
