The MC14500B Handbook (http://www.bitsavers.org/components/motorola/14500/MC14500B_Industrial_Control_Unit_Handbook_1977.pdf http://www.bitsavers.org/components/motorola/14500/MC14500B_...) has detailed designs. Page 1 (pdf 7) has a block diagram. A complete schematic of a system is on page 26 (pdf 32).
- TedDoesntTalk 4y agoWith all of the supporting chips required (instruction counter, etc), why not design something in TTL? What was the advantage of this chip?
- kens 4y agoWell, that's probably why the chip wasn't super-popular :-) The chip reduces your part count somewhat -- it would take a bunch of TTL chips to replace it -- but it's not like a microcontroller that solves your problem entirely.
