* Thermal limiting circuitry on chip will shut down the circuit at a
junction temperature of about 165°C. Continuous operation above
145°C junction temperature may degrade device reliability.
Stresses above those listed under Absolute Maximum Ratings may
cause permanent device failure. Functionality at or above these lim-
its is not implied. Exposure to Absolute Maximum Ratings for ex-
tended periods may affect device reliability.
Package Assembly
Green package devices are assembled with enhanced,
environmental compatible lead-free, halogen-free, and
antimony-free materials. The leads possess a matte-tin
plating which is compatible with conventional board assembly
processes or newer lead-free board assembly processes.
The peak soldering temperature should not exceed 245°C
during printed circuit board

Operating ranges define those limits over which the functionality of
the device is guaranteed by production testing.
* 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 Component
Reliability Assurance Requirements for Telecommunications
Equipment.
