MINMAXUNIT
VCC Supply voltage 1.65 5.5 V
VIH High-level input voltage SCL, SDA VCC = 1.65 V to 5.5 V 0.7 × VCC VCC(1) V
A0, A1, A2, P7–P0 VCC = 1.65 V to 2.7 V 0.7 × VCC 5.5
VCC = 3 V to 5.5 V 0.8 × VCC 5.5
VIL Low-level input voltage SCL, SDA VCC = 1.65 V to 5.5 V –0.5 0.3 × VCC V
A0, A1, A2, P7–P0 VCC = 1.65 V to 2.7 V –0.5 0.3 × VCC
VCC = 3 V to 5.5 V –0.5 0.2 × VCC
IOL Low-level output current(2) P00–P07, P10–P17 Tj ≤ 65°C 25 mA
Tj ≤ 85°C 18
Tj ≤ 100°C 9
INT, SDA Tj ≤ 85°C 6
Tj ≤ 100°C 3
IOH High-level output current Any P-port, P7–P0 –10 mA
ICC Continuous current through GND All P-ports P7-P0, INT, and SDA 200 mA
Continuous current through VCC All P-ports P7-P0 –80
TA Operating free-air temperature –40 85 °C
(1) For voltages applied above VCC, an increase in ICC will result.
(2) The values shown apply to specific junction temperatures, which depend on the RθJA of the package used. See the Calculating Junction Temperature and Power Dissipation section on how to calculate the junction temperature.
