In engineering circles, this circuit is better known as a 7447 BCD to seven-segment decoder/driver, ... This circuit was plotted in DipTrace, and the resulting PCB was sent off to OSHPark.

The demo video below shows the circuit at work, taking the BCD output of a 74HC393 counter — clocked by a 555, naturally — and driving a seven-segment LED.

The 4511 datasheet specifies that this IC is a BCD to 7-segment latch/decoder/driver with four address inputs (DA to DD), an active LOW latch enable input (EL), an active LOW ripple blanking input (BI ...

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 ...
