good day to everyone,
before i give out my request, i would like to lay out a little background on my know how on using logic gates. i have been using this chips without really understanding the why and how the chip funtions. reason is i only follow the circuit diagram of the project that i like. if anyone remembers i have posted here "how to install CMOS chips" reason is everytime i try to build a project i always end up destroying the chip bcoz of mishandling, so i end up using at least 2 chips or sometimes 3 making my project expensive.
since i became a member of this forum, my interest for logic gates has greatly increased, coz i believe i can do lots of you know what with this devises.
so forgive me if i shoot lot of questions regarding this.
Item A: CD4001 - quad NOR & 7402N quad NOR
question 1. do they have same pin configuration?
2. are they interchangeable
3. is there a major difference between the two
Item B: CD4077, CD4030, CD4507 - quadXOR
1. same pin configuration
2. interchangeable
3. major difference
Item C: 7486, 74L86, 74AC86, 74C86N - quad XOR
1. same pin configuration
2. interchangeable
3. can these 74xxx sub with Item B
Thanx :lol:
