(1) All typical values are at nominal supply voltage (1.8-V, 2.5-V, 3.3-V, or 5-V VCC), TA = 25°C.
(2) For operation between specified voltage ranges, refer to the worst-case parameter in both applicable ranges.
(3) The power-on reset circuit resets the I2C bus logic with VCC < VPORF.
(4) RESET = VCC (held high) when all other input voltages, VI = GND.
(5) Cio(ON) depends on internal capacitance and external capacitance added to the SCn lines when channels(s) are ON.
