Hi,

Please let me know the VOL for SCL and SDA. I can find VOL for P-port but there is no specification for SCL and SDA.

Your comment will be appreciated.

Sonoki-san,

This spec is hidden within the IOL spec.

The reason is that the VOL of the device will depend on the IOL current (pull-up resistor values).

VOL would be ~0.4V with a IOL of 3 mA. If you drop your IOL current, then your VOL will drop.
