Impacts to Data Sheet:
None
Change Impact:
None
Reason for Change:
To improve on time delivery performance by qualifying G600V as an addition/alternative mold
compound material for selected PDIP and SPDIP packages at MMT assembly site. Because of
factory shutdowns due to the COVID-19 pandemic, we must quickly implement this change or risk
not having material to ship.
Change Implementation Status:
In Progress
Estimated First Ship Date:
April 30, 2020 (date code: 2018)
NOTE: Please be advised that after the estimated first ship date customers may receive pre and
post change parts.
