Notes
All test data is referenced to 25 C ambient
Operating temperature range -55 C to +125 C
The part temperature (ambient + temp. rise) should not exceed 125 C under worst case operating conditions. Circuit design, component
placement, PWB trace size and thickness, airflow and other cooling provisions all affect the part temperature. Part temperature should be
verified in the end application
