Today, if you can't have a processor: you can still buy some parallel input 7-segment decoders, but they only do BCD (0-10).
You can get decoders with hex support, but they speak serial or I2C in ways that are difficult to drive without software.
You can get exactly one 7-segment IC that does hex and parallel input. It's actually quite fancy and can drive multiple digits and other bells and whistles. It's not _trivial_ to interface with, but _just_ easy enough to do with hardwired circuitry.
