Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted)(1)
MINMAXUNIT
VCCSupply voltage range-0.57V
IIKInput clamp current(2)(VI < 0 or VI > VCC)±20mA
IOKOutput clamp current(2)(VO < 0 or VO > VCC)±20mA
IOContinuous output current(VO = 0 to VCC)±35mA
Continuous current through VCC or GND±70mA
TJJunction temperature150°C
TstgStorage temperature-65150°C
Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
