Hi All,
I want to understand this, if I go for new hardware design should I make the following decisions at the beginning of the design
1. The design should be CMOS based or TTL based in the sense that all the ICs on the board should be supporting either CMOS or TTL?
2. If I go for CMOS based all the ICs I purchase should be of CMOS family and I need to manually check from the IC number whether it belongs to that family and similarly for TTL based design I should buy all the TTL ICs?
3. In case if I buy ICs in which some are CMOS and some are TTL then I should take care of the interfacing circuitry? (as i believe CMOS and TTL are not directly compatible)
4. And finally for every IC will it be mentioned that it is either from CMOS or TTL family?
These questions are giving me lot of confusion.
Thanks in advance,
Regards,
Satya
