DESCRIPTION
The HEF4556B is a dual 1-of-4 decoder/demultiplexer.
Each has two address inputs (A
0
and A
1
), an active LOW
enable input (E) and four mutually exclusive outputs which
are active LOW (O
0
to O
3
). When used as a decoder,
E when HIGH, forces O
0
to O
3
HIGH. When used as a
demultiplexer, the appropriate output is selected by the
information on A
0
and A
1
with E as data input. All
unselected outputs are HIGH.
