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): Standard MLS FACT Products Proposed Date of Change: May 15, 1997 Description of Change: ELIMINATION OF -55C TEST Under the provisions of MIL-PRF-38535, National Semiconductor has eliminated 100% DC/AC production testing and Group A sampling at -55C degrees on the Standard MLS FACT family, which includes: AC, ACT, ACQ, ACTQ, FCT & SCAN logic products. “Standard MLS” is defined as customers requesting Level ‘S’ processing with 883 electricals, with no source control drawing. The electrical drawing for standard MLS is the approved National Semiconductor Military Data Sheet (MDS) for the FACT 883 device type. This does NOT apply to MLS FACT device types with specific customer drawing requirements. This also does NOT apply to JAN S or QML V FACT devices. This process modification was fully qualified and approved by the National Semiconductor Technology Review Board. Effect of Change: Beginning 15-May-97, the 100% -55 degree DC/AC test process will be eliminated on the above mentioned devices. Group B5 Operational life testing will continue to include -55 degree DC/AC testing.
