5.1 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 V or VI > VCC + 0.5 V ±20 mA
IOK Output clamp current(2) VO < -0.5 V or VO > VCC + 0.5 V ±20 mA
IO Continuous output current VO = 0 to VCC ±35 mA
ICC Continuous current through VCC or GND ±70 mA
TJ Junction temperature(3) 150 °C
Tstg Storage temperature –65 150 °C
(1) Operation outside the Absolute Maximum Ratings may cause permanent device damage. Absolute maximum ratings do not imply functional operation of the device at these or any other conditions beyond those listed under Recommended Operating Conditions. If briefly operating outside the Recommended Operating Conditions but within the Absolute Maximum Ratings, the device may not sustain damage, but it may not be fully functional. Operating the device in this manner may affect device reliability, functionality, performance, and shorten the device lifetime.
(2) The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
(3) Assured by design.
