<div>Este k tejto teme by som doplnil
MIC1555 (monostable) a MIC1557 (astable). Idu od 3V do 18V, prva
strana datasheetu uvadza 5MHz a vystupny odpor 15Ohm... Ja som ich
zatial pouzival len na "blikatka", ale v datasheete myslim boli
ukazane aj nejake priklady ako MOSFET budice a podobne...<br>

nahodou neviete o nejakom

0,5MHz, len ja by som

toho MHz. Pripadne neviete o
nejakom inom obvode, ktory by
dokazal generovat obdlznik v

viete o nejakom inom obvode.
