Hello team,
Could you kindly help review below application circuit from my customer?
- Do we need to add pull-up resistors to input/output pins? If yes, how to choose?
- How to choose the series resistors in data line R1/R2/R16/R12? Or we can just remove those resistors?
- For 220pf capacitor, do you think it's ok? Why we need this capacitor?
- Is it necessary to add bidirectional zener?
Thanks.
