Other Parts Discussed in Thread: LM339
Dear expert,
There are some questions about how to handle IN+/IN- when VCC is unpowered.
- Output state when VCC is unpowered?
- Can IN+ or IN- connect with 5V directly without any input resistors when when VCC is unpowered (VCC=0)?
- Any concerns when IN+/- sequence is former than VCC?
Thanks,
Dylan
