elmar Posted August 29, 2008 Share Posted August 29, 2008 SALUT !STIE CINEVA DACA CIRCUITUL INTEGRAT 74HC14N POATE FI INLOCUIT CU DM7404N?VA MULTUMESC ANTICIPAT! Link to comment
vio2007 Posted August 29, 2008 Share Posted August 29, 2008 74HC14N = sase inversoare trigger Schmitt, DM 7404M=sase inversoare simple 74HC14N = 74HCT14N = 74LS14N =74ALS14N = 74AS14N ,ultimile 3CI sunt TTL Link to comment
vio2007 Posted August 29, 2008 Share Posted August 29, 2008 74HC14N=DM7414N?sun echivalente dar DM7414N este TTL si este mai lent decat 74HC14N Link to comment
elmar Posted August 30, 2008 Author Share Posted August 30, 2008 crezi ca ar merge in schema asta? Link to comment
cirip Posted August 30, 2008 Share Posted August 30, 2008 crezi ca ar merge in schema asta? Nu. Daca inversorul nu este cu trigger Schmidt, nu oscileaza oscilatorul de 156KHz, ceea ce face schema nefunctionala. Daca nu gasesti HC14, exista posibilitatea sa sintetizezi un oscilator cu 3 porti inversoare in loc de una singura.Cirip Link to comment
