Hexadecimal 7 segment display driver

BCD or Hexadecimal to Seven Segment Controller General Description The HEX7 IC is a two digit BCD or hexadecimal to seven segment converter. Eight bits of parallel input is converted to drive two seven segment displays. Output polarity control is provided. The HEX7 IC has internal pull resistors on inputs to minimize additional parts. A  · The top design ended up as this: The 4-line to line decoder implementation (24 AND gates and 4 NOT gates): And the line to Hex 7 segment driver ended up like this (7 NOR gates and 22 OR gates): Edit: Fixed the decoder since it was wired to display E instead of 3 Total resources used, 13 pins, 7 macrocells out of 32 total 20 Pterms out.  · Re: 7 Segment Display Driver for Hexadecimal. True that, if the BCD to 7 segment turns off the segments for cases A-F, then you can use the of a decimal 7 segment and add the logic decoding for the A-F cases. On an FPGA you can just draw this using minimal fabric, but that's overkill.

The top design ended up as this: The 4-line to line decoder implementation (24 AND gates and 4 NOT gates): And the line to Hex 7 segment driver ended up like this (7 NOR gates and 22 OR gates): Edit: Fixed the decoder since it was wired to display E instead of 3 Total resources used, 13 pins, 7 macrocells out of 32 total 20 Pterms out. In the event that you would like to have a Hex Driver for a 7-Segment display, but you do not have any GAL22V10s, you can use a GAL16V8 as a driver. However, it will only drive one display. There are several examples of this, listed as examples in several software packages.
