Dual 4-input multiplexer
DESCRIPTION
The HEF4539B is a dual 4-input multiplexer with common
select logic. Each multiplexer has four multiplexer inputs
(I0and I3), 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 (S0to S1) and I0to I3. When E is LOW, S0and
S1determine which multiplexer input (I0to I3) on each of
the multiplexers is routed to the respective multiplexer
output (O).
