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