(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-V, 2.5-V, 3.3-V, 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 when VCC < VPORF.
(5) Cio(ON) depends on the device capacitance and load that is downstream from the device.
