(1) All typical values are at nominal supply voltage (1.8-V, 2.5-V, 3.3-V, or 5-V V_CC), T_A = 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 V_CC < V_PORF.

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

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