(1)

All typical values are at nominal supply voltage (2.5-V, 3.3-V, or 5-V VCC), TA = 25°C.

(2)

The power-on reset circuit resets the I2C bus logic with VCC < VPOR. VCC must be lowered to 0.2 V to reset the device.

(3)

Cio(ON) depends on internal capacitance and external capacitance added to the SCn lines when channels(s) are ON.
