7.1 Absolute Maximum Ratings(1)

over operating free-air temperature range (unless otherwise noted)
MIN MAX UNIT
VCC Supply voltage range –0.5 7 V
VI Input voltage range(2) –0.5 7 V
VO Output voltage range(2) –0.5 VCC + 0.5 V

IOK Output clamp current VO < 0 or VO > VCC ±20 mA
IO Continuous output current VO = 0 to VCC ±25 mA
Continuous current through VCC or GND ±75 mA
(1) 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.
(2) The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
