REASON FOR CHANGE
As part of the integration process resulting from the acquisition of National Semiconductor by Texas Instruments this
past September, it was discovered that both National Semiconductor and Texas Instruments have these 19 identical parts in
their respective product portfolios. As these identical parts may not be pin to pin compatible, it is necessary for customers to
start ordering by the new part numbers to assure receiving the "National Semiconductor" version of the product. Also, while
all 19 of the National Semiconductor versions are leaded (Pb), the Texas Instruments versions in most cases are lead free.
Customers can start ordering immediately by the new part number and must transition to the new ordering part number by 30th
June 2012.
