This is to advise you that a Design and/or Process Change will be made to the following High Reliability product(s):
Product ID (Description): Level B/Q JL/LM111 products
Proposed Date of Change: Datecode 0226 and onward
Description of Change: The LM111 Level B/Q devices manufactured after the above datecode will no longer have 100% production burn-in. A burn-in process monitor has been established to ensure continued quality and reliability. Operational life burn-in will continue to be performed on LM111 Jan B and /883 product per standard Quality Conformance Inspection rules.
This reduction does not affect any Level S, Level S / Level B Rad Tolerant, JAN S, or Custom -MLS products.
Under the guidelines of MIL-PRF-38535 QML process reduction procedures, National Semiconductor's Technology Review Board has reviewed and approved this process modification.
