6.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted)(1)
MIN MAX UNIT
VCC Supply voltage –0.5 7 V
IIK Input clamp current(2) VI < –0.5 or VI > VCC + 0.5 ±20 mA
IOK Output clamp current(2) VO < –0.5 or VO > VCC + 0.5 ±20 mA
IO Continuous output current VO = 0 to VCC ±35 mA
Continuous current through VCC or GND ±70 mA
TJ Junction temperature(3) 150 °C
Tstg Storage temperature –65 150 °C
(1) Stresses beyond those listed under Absolute Maximum Rating 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 Condition. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) The input and output voltage ratings may be exceeded if the input and output current ratings are observed. Do not exceed the absolute maximum voltage supply rating. 
(3) Guaranteed by design.
