7.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted) (1)(3)(4)
MIN MAX UNIT
Supply voltage –0.3 6 V
Voltage at SMBDAT, SMBCLK,
TCRIT1, TCRIT2, TCRIT3 		–0.5 6 V
Voltage at other pins –0.3 VDD + 0.3 V
D− Input current ±1 mA
Input current at all other pins (2) ±5 mA
Package input current (2) 30 mA
SMBDAT, TCRIT1, TCRIT2,
TCRIT3 output sink current		 10 mA
Storage temperature, Tstg –65 150 °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.
(2) When the input voltage (VI) at any pin exceeds the power supplies (VI < GND or VI > VDD), the current at that pin must be limited to 5 mA. Parasitic components and or ESD protection circuitry are shown in the table below for the LM95214's pins.
(3) Soldering process must comply with reflow temperature profile specifications. Refer to http://www.ti.com/packaging
(4) Reflow temperature profiles are different for packages containing lead (Pb) than for those that do not.
