5.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted)(1)
MIN MAX UNIT
VDD Supply voltage(2) 18 V
VI Input voltage, any input –0.3 VDD V
Sink current, discharge or output 150 mA
IO Source current, output 15 mA
Continuous total power rating(3) TA ≤ 25°C 900 mW
TA = 125°C 180
Continuous total power dissipation derating factor(3), TA ≥ 25°C 7.2 mW/°C
TA Operating free-air temperature –40 125 °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 used outside the Recommended Operating Conditions but within the Absolute Maximum Ratings, the device may not be fully functional, and this may affect device reliability, functionality, performance, and shorten the device lifetime.
(2) All voltage values are with respect to network GND.
