IIOK Input/output clamp current VO < 0 or VO > VCC –20 μA
IOL Continuous output low current VO = 0 to VCC 50 mA
IOH Continuous output high current VO = 0 to VCC –50 mA
ICC Continuous current through GND –250 mA
Continuous current through VCC 160
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 Recommend Operating Conditions. If briefly operating outside the Recommend 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 negative-voltage and output voltage ratings may be exceeded if the input and output current ratings are observed.
