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
Table 1. Ordering information
All types operate from 40 C to +85 C.

[1] The typical values of the propagation delay and transition times are calculated from the extrapolation formulas shown (CL in pF).
[2] Transition time tt is the same as the HIGH to LOW and LOW to HIGH transition times tTHL and tTLH.
