As dori, daca se poate ceva ajutor cu niste circuite integrate mai vechi, romanesti. Inlocuitori pentru: E555, A741, E565, CDB400E, CDB474E. De asemenea informatii despre: CDB413EM, CDB404E, CDB408E, CDB413E, CDB4121E, CDB420E, CDB408HE, CDB400HE, CDBG34121E.Va multumesc!

E555 probabil ca e NE555, A741 = UA741 dar in orice aplicatie legata de audio exista la ora actuala operationale mult mai bune si la fel de ieftine ex NE5532 sau TL072. Celelalte sunt circuite logice, nu am lucrat cu asa ceva asa ca nu o sa'mi dau cu presupusul.

Din cartea "Agenda radioelectronistului" avem asa: CDB400E sau CDB400HE =operator cvadruplu Si-Nu cu 2 intrari. CDB474E=cicuit basculant bistabil dublu de tip D CDB413E sau EM=operator dublu Si-Nu tip "trigger Schmitt" cu 4 intrari CDB404E=inversor sextuplu CDB4121E=Circuit basculant monostabil. CDB420E=Operator dublu Si-Nu cu 4 intrari CDB408E=operator cvadruplu SI cu 2 intrari Tie iti trebuie si alocarea pinilor , poate poti face rost de carte.

BetaE555 = LM555, NE555, SA555 compatibile pin cu pin.

BetaA741 = ULA6741, ULA7741,UA741, LM741 si merge inlocuit cu TL071, TL081, NE5534, OPA132, OPA134. Daca schema utilizeaza mai multe operationale, atunci poti utiliza si integrate care au in capsula doua operationale (TL072, TL082, NE5532, RC4558, MC1458, OPA2604, OPA2132, OPA2134) sau patru operationale (TL074, TL084, OPA4132, OPA4134).

In ceeace ce priveste circuitele logice TTL, este bine sa consulti un catalog dupa cele precizate mai sus de craciun.
