over operating free-air temperature range (unless otherwise noted) (1)
MINMAXUNIT
VCCSupply voltage–0.56V
VIInput voltage(2)–0.56V
VOOutput voltage(2)–0.56V
IIKInput clamp currentVI < 0–20mA
IOKOutput clamp currentVO < 0–20mA
IIOKInput/output clamp currentVO < 0 or VO > VCC±20mA
IOLContinuous output low currentVO = 0 to VCC50mA
IOHContinuous output high currentVO = 0 to VCC–50mA
ICCContinuous current through GND–250mA
Continuous current through VCC160
TstgStorage temperature–65150°C
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) The input negative-voltage and output voltage ratings may be exceeded if the input and output current ratings are observed.
