DESCRIPTION
The HEF4556B is a dual 1-of-4 decoder/demultiplexer.
Each has two address inputs (A0 and A1), an active LOW
enable input (E) and four mutually exclusive outputs which
are active LOW (O0 to O3). When used as a decoder,
E when HIGH, forces O0 to O3 HIGH. When used as a
demultiplexer, the appropriate output is selected by the
information on A0 and A1 with E as data input. All
unselected outputs are HIGH.
