Product data sheet

General description
The HEF4555B contains two 1-of-4 decoders/demultiplexers.
Each has two address inputs (nA0 and nA1, an active LOW enable input (nE) and four mutually exclusive outputs which are active HIGH (nY0 to nY3).
When used as a decoder, nE when HIGH, forces nY0 to nY3 LOW.
When used as a demultiplexer, the appropriate output is selected by the information on nA0 and nA1 with nE as data input.
All unselected outputs are LOW.
It operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS (usually ground).
Unused inputs must be connected to VDD, VSS, or another input.
