(1) All typical values are at nominal supply voltage (V_CC = 1.8 V, 2.5 V, 3.3 V, or 5 V), T_A = 25°C.

(2) The power-on reset circuit resets the I²C bus logic with V_CC < V_PORF.

(3) C_io(ON) depends on the device capacitance and load that is downstream from the device.

(4) RESET = V_CC (held high) when all other input voltages, V_I = GND
