 
HEF4555B
1-of-4 decoder/demultiplexer
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.
Features and benefits
- Wide supply voltage range from 3.0 V to 15.0 V 
- CMOS low power dissipation 
- High noise immunity 
- Fully static operation 
- 5 V, 10 V, and 15 V parametric ratings 
- Standardized symmetrical output characteristics 
- Complies with JEDEC standard JESD 13-B 
- ESD protection: - HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V 
- CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V 
 
- Specified from -40 °C to +85 °C 
Applications
- Code conversion 
- Address decoding 
- Demultiplexing: when using the enable input as data input
