Quadruple 2-input multiplexer

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 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).
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.
