Hi Adrian,

Thank you for reaching out on E2E.

The pin capacitance of SCL and SDA pins are not characterized and not specified in the datasheet.
It is recommended to estimate this with a value of 10 pF maximum
As in compliance with the standard I2C specs, there is a 50 ns max deglitch filter for fast mode.
Output low level sink current is given as 2mA:

Hope this helps to answer your questions.

Best Regards,
Sarah

Hi Adrian,

Unfortunately we do not have any IBIS model for the LP8725. This is an older device with limited resource support.

Apologies for the inconvenience.

Best Regards,
Sarah
