In this case, the end product is a binary-to-seven-segment decoder built from scratch. In engineering circles, this circuit is better known as a 7447 BCD to seven-segment decoder/driver, ...

When we think of 7-segment displays as the ubiquitous LED devices that sprung into popularity in the 1970s. However, numbers have existed for a lot longer than that, and people have wanted to know … ...

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 ...
