(2) Each I/O must be externally limited to a maximum of 25 mA, and each octal (P07–P00 and P17–P10) must be limited to a maximum current of 100 mA, for a device total of 200 mA. (3) The total current sourced by all I/Os must be limited to 160 mA (80 mA for P07–P00 and 80 mA for P17–P10). 6.5 Electrical Characteristics over recommended operating free-air temperature range (unless otherwise noted) PARAMETER TEST CONDITIONS VCC MIN TYP(1) MAX UNIT VIK Input diode clamp voltage II = –18 mA 1.65 V to 5.5 V –1.2 V VPORR Power-on reset voltage, VCC rising VI = VCC or GND, IO = 0 1.2 1.5 V VPORF Power-on reset voltage, VCC falling VI = VCC or GND, IO = 0 0.75 1 V VOH P-port high-level output voltage(2) IOH = –8 mA 1.65 V 1.2 V 2.3 V 1.8 3 V 2.6 4.75 V 4.1 IOH = –10 mA 1.65 V 1 2.3 V 1.7 3 V 2.5 4.75 V 4 IOL Low-level output current SDA VOL = 0.4 V 1.65 V to 5.5 V 3 mA P port(3) VOL = 0.5 V 1.65 V to 5.5 V 8 VOL = 0.7 V 1.65 V to 5.5 V 10 INT VOL = 0.4 V 1.65 V to 5.5 V 3 II Input leakage current SCL, SDA Input leakage VI = VCC or GND 1.65 V to 5.5 V ±1 μA A2–A0 Input leakage VI = VCC or GND 1.65 V to 5.5 V ±1 IIH Input high leakage current P port VI = VCC 1.65 V to 5.5 V 1 μA IIL Input low leakage current P port VI = GND 1.65 V to 5.5 V –1 μA |
