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. The maximum package power dissipation is calculated using a junction temperature of 150 °C and a board trace length of 75 mils. For more information, refer to the Package Thermal Considerations application note in the 1994 ABT Advanced BiCMOS Technology Data Book, literature number SCBD002B. |
