1. General description
The HEF4028B is a 4-bit BCD to decimal decoder, a 4-bit BCO to octal decoder with
active LOW enable or an 8-output (Y0 to Y7) inverting demultiplexer. The outputs are fully
buffered for best performance.
When used as a BCD to decimal decoder a 1-2-4-8 BCD code applied to inputs A0 to A3
causes the selected output to be HIGH. The other nine outputs will be LOW.
To use the HEF4028B as a BCO to octal decoder, input A3 is an active LOW enable pin
and outputs Y8 and Y9 are not used. A 1-2-4 BCO code applied to inputs A0 to A2 causes
the selected output (Y0 to Y7) to be HIGH. The other seven outputs will be LOW. When
A3 is HIGH outputs (Y0 to Y7) will be forced LOW.
When used as an 8-output (Y0 to Y7) inverting demultiplexer A0 to A2 are used as
address inputs and A3 is the data input. Outputs Y8 and Y9 are not used.
It operates over a recommended V
DD
power supply range of 3 V to 15 V referenced to V
SS
(usually ground). Unused inputs must be connected to V
DD
, V
SS
, or another input. It is
also suitable for use over the full industrial (
40
C to +85
C) temperature range.
2. Features and benefits
