‡ _{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.
NOTE 1: The maximum package power dissipation is calculated using a junction temperature of 150°C and a board trace length of 300 mils,
except for the N package, which has a trace length of zero. For more information, refer to the Package Thermal Considerations
application note in the 1994 ABT Advanced BiCMOS Technology Data Book, literature number SCBD002B.
