The CD4028BE is a 4-bit binary to BCD (Binary-Coded Decimal) converter. It has 16 pins. Here’s a brief overview of its pin functions:
1. VDD (Pin 1): Positive power supply.
2. GND (Pin 8): Ground connection.
3. A, B, C, D (Pins 2-5): Binary inputs for the 4-bit binary number.
4. E (Pin 6): Enable input (active high).
5. I0 - I9 (Pins 7, 9-15): BCD output (binary-coded decimal) corresponding to input values.
6. G (Pin 10): Group output (indicates if the input is valid for BCD).
7. VSS (Pin 11): Negative power supply (usually connected to GND in single supply configurations).
The device converts the 4-bit binary input into a 4-bit BCD output, indicating values from 0 to 9, with the Group output signaling when the input exceeds BCD limits.
