Hello
What is the output impedance of B-port outputs, if the A-port is driven at 3.3V and the B-port at 2.5V?
Best Regards

The B-port drive strength depends only on the B supply voltage.
The output impedance can be derived from the VOx/IOx values (see [FAQ] What is the output voltage (VOH or VOL) when the output current is X or the supply voltage is Y?). At 2.5 V, the worst-case value is 61.1 Ω; the typical value is about half that.
