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. This current will only flow 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.
For more information, refer to the Package Thermal Considerationsapplication note in the ABT Advanced BiCMOS Technology Data
Book literature number SCBD002.
