Hello,

Do we have IBIS model for TPS25990?

This one does not work for me.

This is the only IBIS model we have.

Any IBIS model that has the similar buffer behavior to TPS25990 I2C interface that I can use as a replacement?

Hi, Avishek. Thank you for your reply.
However, the IBIS model /cfs-file/__key/communityserver-discussions-components-files/196/tps25990.ibs pins does not align with the datasheet.
IBIS model on the left side below showing I2C pins at pin4 (SCL) and pin5 (SDA) while the datasheet showing I2C pins at pin15 (SDA) and pin 16 (SCL).
Is there any explanation for this?

TPS25990 has six (6) GPIOs. Arbitrary Pin 1 to 6 are considered in the model for six GPIOs. These are not exact pin numbers.
