Part Number: SN75C1167

Hi Team,

Recommended operating condition of driver output current shows the following.



question1)
Is ±20mA defined as per single driver?
I believe it but would like to confirm just in case.

question2)
What is concern if output current of driver (1ch) exceeds ±20mA?
My customer estimates it exceeds ±20mA. It is approximately ±21~22mA.

Best Regards,

  • Yaita san,

    It is 20mA per driver port pin.

    22 mA is fine. There is margin before any current limit.
