Nand cu and open collector

Recommended Posts

Se poate combina o poarta NAND cu una AND ambele de tipul open collector ( drain )  ca in schema ? Dupa logica mea nu ar fi nici o problema dar astept parerile celor mai experimentati.

Multumesc.

Conectarea în paralel a ieșirilor Open Collector nu reprezintă nicio problemă . Pot fi chiar familii diferite dacă au aceași tensiune de alimentare - exemplu LS cu HC(T) . 

Mai rămâne de verificat ca funcția logică realizată să fie cea dorită.
