#166635 - standard 8051 Responding to: Jan Waclawek's previous message |
Jan Waclawek said:
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...? Oh, sorry. I haven't used a "standard" 8051 in fifteen years. We're all SiLabs, all the time here. -a |
