87 BCD to 7-Segment Decoder

87 : BCD to 7-Segment Decoder


How it works

The IC accepts four binary-coded decimal input signals, and generates a corresponding 7-segment output signal

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


# Input Output
0 input 1 (BCD 1) segment a
1 input 2 (BCD 2) segment b
2 input 3 (BCD 4) segment c
3 input 4 (BCD 8) segment d
4 decimal dot (passthrough) segment e
5 output invert segment f
6 none segment g
7 none segment dot
