These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) The input and output negative-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. (4) For the DW package: above 70°C the value of Ptot derates linearly with 8 mW/K. (5) For the DB, DGV, N, NS, and PW packages: above 60°C the value of Ptot derates linearly with 5.5 mW/K. 6 Specifications 6.1 Absolute Maximum Ratings over operating free-air temperature range (unless otherwise noted) (1) MIN MAX UNIT VCC Supply voltage range –0.5 6.5 V VI Input voltage range(2) –0.5 6.5 V VO Voltage range applied to any output in the high-impedance or power-off state (2) –0.5 6.5 V VO Voltage range applied to any output in the high or low state (2)(3) –0.5 VCC + 0.5 V IIK Input clamp current VI < 0 –50 mA IOK Output clamp current VO < 0 –50 mA IO Continuous output current ±50 mA Continuous current through VCC or GND ±100 mA Ptot Power dissipation TA = –40°C to +125°C (4) (5) 500 mW Tstg Storage temperature –65 150 °C TJ Junction temperature 150 °C |
