  • Author: JinGen Lim
  • Description: Converts a 4-bit BCD input into a hexadecimal 7-segment display output
  • GitHub repository
  • Clock: 0 Hz

How it works

The IC accepts four binary-coded decimal input signals, and generates a corresponding hexadecimal 7-segment output signal. Segment outputs may be inverted with the INVERT pin to support both common cathode/anode displays.

How to test

Connect the segment outputs to a 7-segment display. Configure the input (IN0:0, IN1:2, IN2:4, IN3:8). The input value will be shown on the 7-segment display
