I'm trying to find a 7-segment display BCD decoder IC with normal HEX display.

Most of the decoders that I managed to find have an output like this:

These hex values just look awful. I previously did this decoder on FPGA, and the output looked like this:

A b C d E F

Does anyone know some BCD decoder IC with "normal" HEX display?

    \$\begingroup\$ A binary-coded decimal decoder wouldn't do that - if it did it would be called a seven-segment hexadecimal decoder instead. And apparently they don't make those. \$\endgroup\$ – Andrew Morton Mar 21 '18 at 10:13

  • \$\begingroup\$ This question (not exactly a duplicate) and its answers mention the MC14495-P1 (seemingly difficult to get hold of, hence the question) and a Fairchild part DM9368 (data sheet) which I have no idea about the availability of. \$\endgroup\$ – TripeHound Mar 21 '18 at 11:14

    \$\begingroup\$ Used to use a TTL PROM or MOS EPROM for this. Today I would probably use a PIC with 11 or more i/o pins. \$\endgroup\$ – AlmostDone Mar 21 '18 at 12:08

I have no idea on the availability of these chips:

  • V40511 (this one is an old DDR (eastern Germany) part, so definitely gone)
  • MC14495
  • DM9368
  • D345
  • D346
  • D348
  • CMOS 4311 or 4368
  • 74C915 ?
  • ICM7211 / ICM7212 (not the A variant)

The TIL311 is a complete hexadecimal display - might be an alternative.
