Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted)(1)
MINMAXUNIT
VCCSupply voltage–0.56.5V
VIInput voltage(2)–0.56.5V
VOVoltage range applied to any output in the high-impedance or power-off state(2)–0.56.5V
VOVoltage range applied to any output in the high or low state(2)(3)–0.5VCC + 0.5V
IIKInput clamp currentVI < 0–50mA
IOKOutput clamp currentVO < 0–50mA
IOContinuous output current±50mA
Continuous current through VCC or GND±100mA
PtotPower dissipationTA = –40°C to +125°C(4)(5)500mW
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 Section 5.3 is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
The input and output negative-voltage ratings may be exceeded if the input and output current ratings are observed.
The value of VCC is provided in the Section 5.3 table.
For the DW package: above 70°C the value of Ptot derates linearly with 8mW/K.
For the DB, DGV, N, NS, and PW packages: above 60°C the value of Ptot derates linearly with 5.5mW/K.
