β E 555E generator de functii


JQ

Recommended Posts

Salutare, sper ca am nimerit unde trebuie.As dori sa fac un generator de frecvente si am gasit foarte multe scheme cu un oscilator 555 care din cate stiu eu are cel putin 30 de ani :).De la magazin am luat un β E 555E 89.29 care are 14 pini.Se pare ca NE555 are doar 8, mai exista niste NE555F care are 14.As vrea sa stiu dupa care datasheet sa ma iau, se potriveste cel din urma cu ce-l pe care l-am cumparat? Stiti vreun echivalent? merci
