The hexadecimal to seven segment encoder has 4 bit input and 7 output. Depending upon the input number, some of the 7 segments are displayed. The seven segments are represented as a, b, c, d, e, f, g. A high on one of these segments make it display. Hex-to-7-Segment Decoder: Logic Equations To display hexadecimal digits on a 7-segment display, we need to design a hex-to-7-segment decoder (called hex7seg), whose input is a 4-bit number (x3:0), and outputs are the 7-segment values a – g given by the truth table above. We can make a Karnaugh map for each segment and then develop.

7 Segment Hex Code Chart
A very simple question here.
So there's the common chips like 4511 and 7447 which will do 4-bit BCD to 7-segment display... But, that leaves out the other 6 binary combinations, which we commonly represent as A-F.
Is there a single-chip 7-segment decoder that will display the full range of 4-bit values, 0-F?
Also, does anyone make an SMD version of 7447? I couldn't find one.
Help is appreciated.
