These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) The input negative-voltage and output voltage ratings may be exceeded if the input and output current ratings are observed. 6 Specifications 6.1 Absolute Maximum Ratings (1) over operating free-air temperature range (unless otherwise noted) MIN MAX UNIT VCC Supply voltage –0.5 6 V VI Input voltage (2) –0.5 6 V VO Output voltage(2) –0.5 6 V IIK Input clamp current VI < 0 –20 mA IOK Output clamp current VO < 0 –20 mA IIOK Input-output clamp current VO < 0 or VO > VCC ±20 mA IOL Continuous output low current through a single P-port VO = 0 to VCC 50 mA IOH Continuous output high current through a single P-port VO = 0 to VCC –50 mA ICC Continuous current through GND by all P-ports, INT, and SDA 250 mA Continuous current through VCC by all P-ports –160 Tstg Storage temperature –65 150 °C (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 500-V HBM is possible with the necessary precautions. (2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 250-V CDM is possible with the necessary precautions. 6.2 ESD Ratings VALUE UNIT V(ESD) Electrostatic discharge Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) 2000 V Charged-device model (CDM), per JEDEC specification JESD22-C101(2) 1000 (1) The SCL and SDA pins shall not be at a higher potential than the supply voltage VCC in the application, or an increase in supply current, ICC, will result. 6.3 Recommended Operating Conditions MIN MAX UNIT 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, RESET, 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, RESET, 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 Any P-port, P7–P0 25 mA 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 |
