6.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted) (1)
MIN MAX UNIT
Supply voltage, VS 4 V
Input voltage SDA, SCL, ALERT, A2, A1 -0.3 4 V
A0 -0.3 (VS) + 0.3 V
Sink current SDA, ALERT 10 mA
Operating junction temperature -55 150 °C
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. 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.

6.2 Handling Ratings

MIN MAX UNIT
Tstg Storage temperature range -60 150 °C
V(ESD) Electrostatic discharge Human body model (HBM), per ANSI/ESDA/JEDEC JS-001, all pins(1) –2000 2000 V
