HEF4028B Product details

1. General description
The HEF4028B is a 4-bit BCD to 1-of-10 decoder. A 1-2-4-8 BCD code applied to inputs A0 to A3
causes the selected output to be HIGH, the other nine will be LOW. To use as a 1-of-8 decoder with
enable, 3-bit octal inputs are applied to inputs A0 , A1 and A2 selecting an output Y0 to Y7 . Input
A3 then becomes an active LOW enable, forcing the selected output LOW when A3 is HIGH. The
device may also be used as an 8-output (Y0 to Y7) demultiplexer with A0 to A2 as address inputs
and A3 as an active LOW data input. Inputs include clamp diodes. This enables the use of current
limiting resistors to interface inputs to voltages in excess of VDD.
2. 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 JESD22-A114F exceeds 2000 V
• MM JESD22-A115-B exceeds 200 V
• Specified from -40 °C to +85 °C
