If you've got a processor and sufficient suitable output lines, it's trivial to do the nybble-to-7-segment encoding in software in the processor - so adding a separate chip to do it is just a waste. Well, 30 years ago it wasn't so trivial, was it? Bloody hell, by no means did I want to recommend the use of an "9368" here, only wallowing a bit in memories... Kai |
