Part Number: LM311
Tool/software:
I'm using LM311 to make a zero crossing detector.
The low to high response time is 112ns, however the high to low response time is 1.35us, much longer than excpected.
I replaced the chip twice, nothing changed, what the chip acted is against the PSpice simulation result which is 154ns.
