OBSOLETE PRODUCTS LISTING

National Semiconductor's Obsolete Product Listing enables you to find those products for which National has issued Lifetime Buy notification. You may access these products alphanumerically or by date. The listing provides the last date to buy these products as well as any alternate National products or alternate vendors, if the information is available to us.

National Semiconductor make every commercially reasonable effort possible to announce one (1) year in advance of its intention to obsolete any standard product previously released for production. Customers may place final orders within that one year period and shall have fifteen (15) months from the effective date of the obsolescence announcement to schedule final delivery. The "LTB Expiration Date" is the last date on which we accepted final production orders. No orders are accepted after that date.
