A display decoder is used to convert a BCD or a binary code into a 7 segment code used to operate a 7 segment LED display. Here we design a simple display decoder circuit using logic gates. A display ...

[spencerhamblin] is starting his explorations into digital electronics the hard way: reproducing a “simple” IC’s functionality by wiring up a board full of discrete transistors. In this case, the end ...

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, ...
