#166632 - NPN and standard '51? Responding to: ???'s previous message |
I would be afraid of being able to switch 100mA safely by NPN connected directly to a relatively standard '51, capable of sourcing... a few hundreds of uA?
But I don't have any practical experience with this, I admit. Maybe it's okay...? JW |
