Even though commercial BCD to 7 segment decoders are available, designing a display decoder using logic gates may prove to be beneficial from economical as well as knowledge point of view. Circuit ...

In this tutorial we are going to drive 7-segment display with IC 4511. This CD4511 IC is basically a BCD to 7-Segment decoder/driver IC ... but then we need 3 more pins and circuit will be complex, ...

The circuit works off a 5V regulated power supply. It is built around priority encoder IC 74HC147 (IC1), BCD-to-7-segment decoder IC CD4511 (IC2), 7-segment display LTS543 (DIS1), and a few discrete ...
