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 may be exceeded if the input and output clamp-current ratings are observed.
2. This current flows only when the output is in the high state and VO > VCC.
3. The maximum package power dissipation is calculated using a junction temperature of 150
°C and a board trace length of 750 mils.

Package Thermal Considerations application note in the 1994 ABT Advanced BiCMOS Technology
Data Book, literature number SCBD002B.
