1-of-4 decoder/demultiplexer

Rev. 7 — 15 October 2018

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
