INTEGRATED CIRCUITS DATA SHEET For a complete data sheet, please also download: · The IC04 LOCMOS HE4000B Logic Family Specifications HEF, HEC · The IC04 LOCMOS HE4000B Logic Package Outlines/Information HEF, HEC HEF4555B MSI Dual 1-of-4 decoder/demultiplexer Product specification File under Integrated Circuits, IC04 January 1995 Philips Semiconductors Product specification 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. HEF4555B MSI Fig.2 Pinning diagram.
