ELECTRICAL CHARACTERISTICS
Absolute Maximum Ratings
Stresses greater than those listed under Absolute Maximum Ratings can cause permanent device failure. Functionality at or
above these limits is not implied. Exposure to absolute maximum ratings for extended periods can affect device reliability.

Note:
Thermal limiting circuitry on chip will shut down the circuit at a junction temperature of about 165° C. Operation above 145° C junction temperature
may degrade device reliability.

Thermal Resistance
The junction to air thermal resistance of the Le79R101 device in a 32-pin PLCC package is 45° C/W. The typical junction to case
thermal resistance is 14° C/W. Measured under free air convection conditions and without external heat-sinking.
Electrical Operating Ranges
Legerity guarantees the performance of this device over commercial (0
°
to 70
°
C) and industrial (−40
°
to 85
°
C) temperature
ranges by conducting electrical characterization over each range, and by conducting a production test with single insertion
coupled to periodic sampling. These characterization and test procedures comply with section 4.6.2 of Bellcore TR-TSY-000357
