4.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted)(1)
MIN MAX UNIT
VCC Supply voltage -0.5 6 V
IIK Input diode current (VI < -0.5V or VI > VCC + 0.5V) ±20 mA
IOK Output diode current (VI < -0.5V or VI > VCC + 0.5V) ±50 mA
IO Output source or sink current per output pin VO < -0.5V or VO > VCC + 0.5V ±50 mA
VCC or ground current, ICC or IGND (2) ±100 mA
TJ Maximum junction temperature (plastic package) 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 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) For up to 4 outputs per device, add ±25mA for each additional output.
