HEF4555B

1-of-4 decoder/demultiplexer

Rev. 5 — 18 November 2011

Product data sheet

1. 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.

2. Features and benefits

 Fully static operation

 5 V, 10 V, and 15 V parametric ratings

 Standardized symmetrical output characteristics

 Specified from 40 C to +85 C

 Complies with JEDEC standard JESD 13-B

3. Applications

 Code conversion

 Address decoding

 Demultiplexing: when using the enable input as data input

4. Ordering information
