In engineering circles, this circuit is better known as a 7447 BCD to seven-segment decoder/driver, but just using a single chip has little pedagogical value.

The circuit is designed to map 4-bit binary inputs to the segments of a seven-segment display. The truth table and logic for each segment are implemented using basic logic gates (AND, OR, NOT). If you ...

Usually, almost all 7-segment decoder ICs have a blanking input (RBI) connection to imply this type of brightness control. Because, the frequency in picture is above 50 Hz, unwanted flickering effect ...

Many options exist to drive seven-segment LED displays, but most are limited to low output currents. The approach described here uses one 74ALS374 or 74AS374 octal latch, wired as a shift register ...
