Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. 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.
NOTES:
1. The input and output negative-voltage ratings can be exceeded if the input and output clamp-current ratings are observed.
2. For the SN74ABT18504 (PM package), the power derating factor for ambient temperatures greater than 55
°C is –10.5 mW/°C.
