5.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted) (1)
MINMAXUNIT
VCCSupply voltage range–0.56.5V
VIInput voltage range(2)–0.56.5V
VOVoltage range applied to any output in the high-impedance or power-off state(2)–0.56.5V
VOVoltage range applied to any output in the high or low state(2)(3)–0.5VCC + 0.5V
IIKInput clamp currentVI < 0–50mA
IOKOutput clamp currentVO < 0–50mA
IOContinuous output current±50mA
Continuous current through VCC or GND±100mA
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 negative-voltage and output voltage ratings may be exceeded if the input and output current ratings are observed.
(3) The value of VCC is provided in the Recommended Operating Conditions table.
