* Zarlink guarantees the performance of this device over commercial (0 to 70º C) and industrial (-40 to 85ºC) 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 GR-357-CORE Component
Reliability Assurance Requirements for Telecommunications Equipment.
Package Assembly
The standard (non-green) package devices are assembled with industry-standard mold compounds, and the leads possess a tin/
lead (Sn/Pb) plating. These packages are compatible with conventional SnPb eutectic solder board assembly processes. The
peak soldering temperature should not exceed 225°C during printed circuit board assembly.
The green package devices are assembled with enhanced environmental compatible lead (Pb), halogen, 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 assembly.
Refer to IPC/JEDEC J-Std-020B Table 5-2 for the recommended solder reflow temperature profile
