Hi, Ramius

I see 25 pf as emitter capacitance ... ( see datasheet - Philips p.5 )

Also have a look to the used components for the switching time tests ...

Your comments ???

Now ... your delays are quite long ... could you tell what make you call them " false " ???


But looking at your program closer ... The false delays are obvious - but for some µs only @ each loop ...

do not shoot your transistor, but your program lines ...
