Dual 1-of-4 decoder/demultiplexer

DESCRIPTION

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 LOW. 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 LOW.
