DESCRIPTION
The HEF4539B is a dual 4-input multiplexer with common
select logic. Each multiplexer has four multiplexer inputs
(I
0
and I
3
), an active LOW enable input (E) and a
multiplexer output (O). When HIGH, E forces O of the
respective multiplexer LOW, independent of the select
inputs (S
0
to S
1
) and I
0
to I
3
. When E is LOW, S
0
and
S
1
determine which multiplexer input (I
0
to I
3
) on each of
the multiplexers is routed to the respective multiplexer
output (O).
