54L ALERT BxA response summary

Abstract

On 14 July 1971 MSC issued an ALERT (MSC-71-04) on Texas Instruments 54L series integrated circuits. This ALERT indicated that devices manufactured prior to the second week of August 1971 may contain conductive particulate contaminants. Subsequently Bendix received LSPO letter EHZ/10-8/L-505/B requesting a response as to the usage and the potential hardware impact on Array E. This ATM reviews the problem and summarizes the BxA response activities. Revision A reflects the anticipated distribution of screened devices in Array E hardware, additional parts screening and failure analysis results, and a comparison of different logic devices and assembly areas at TI-Dallas.
