Group,
What are the relative merits of the various logic families HCT, HC, AC, ACT
with regard to generating RFI?
I remember one time we replaced an HCT which made more noise than Schottky
TTL due to an internal overlap in the switching causing a power rail
"shorting" spike.
I'm sure by now that most IC vendors have addressed the EMC problems
associated with poorly designed chips, but what's the status on these now?
What's the order of preference? Which one's best?
