BCDto7seg
BCDto7seg (BCD to 7-segment) refers to a class of digital circuits that convert a binary-coded decimal input into the seven-segment control signals needed to drive a seven-segment display. The input is typically a 4-bit BCD value representing decimal digits 0 through 9. The circuit maps these values to the seven segment lines (labeled a through g) so that the corresponding numeral is shown on the display.
Most implementations are combinational decoders or decoders/drivers. They may also provide a decimal point output and
BCDto7seg devices are commonly integrated as stand-alone decoder/driver ICs or as parts of microcontroller peripherals. They
Common examples include parts from the 4511 family (BCD-to-7-segment for common-cathode displays) and the 7447 family
