HEF4555B decoder/demultiplexer equivalent, dual 1-of-4 decoder/demultiplexer.
for the HEF4555B are:
* Code conversion.
* Address decoding.
* Demultiplexing: when using the enable input a.
The HEF4555B 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 HIGH (O0 to O3). When used as a decoder, E when HIGH, forces O0 to O3 LO.
