Hello List, Hello Ference!
Regarding the topics we had today in the Mumble session:
1. here is a small discussion about the Schmitt-Trigger I had in mind, which points also to *both* sources I am aware of
https://electronics.stackexchange.com/questions/301158/cmos-schmitt-trigger-...
2. attached a data book scan regarding TTL input current (I_iL, I_iH) - sorry in German only - for some TTL families. While nobody is using 74xx anymore, I guess we should be comparable to a 74LSxx standard input-load with our TTL Input Pad.
Best Regards, Hagen.
