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 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

Bn).

MSI

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.
