Quadruple 2-input multiplexer
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.
DESCRIPTION
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.
