REPLACEMENT STRATEGY FOR OBSOLETE INTEGRATED CIRCUITS

RA ASSOCIATES PROPOSES TO INVESTIGATE SOLUTIONS TO THE PROBLEM OF OBSOLETE INTEGRATED CIRCUITS. THIS WILL INCLUDE A SURVEY AND COMPILATION OF THE WORK UNDERWAY BY OTHERS, PLUS AN INDEPTH ANALYSIS OF SEVERAL CANDIDATE SOLUTIONS. SPECIFIC CANDIDATES INCLUDE 54ALS, 54HCT, 54ACT LOGIC FAMILITES. A SOLUTION IS PROPOSED FOR THOSE CASES WHERE THE PINOUT NEEDED IS NOT AVAILABLE. COMPUTER ANALYSIS OF EFFECTS OF REPLACEMENT WILL BE AUGMENTED WITH MANUAL ANALYSIS, TO ARRIVE AT A STRATEGY, OR GROUP OF STRATEGIES, WHICH WILL SOLVE MOST, IF NOT ALL, CASES. REPLACEMENT STRATEGY WILL BE TESTED USING ACTUAL OR SIMULATED BOARDS, UNDER MILITARY TEMPERATURE CONDITIONS. A COMPREHENSIVE FINAL REPORT WILL BE PREPARED. DURING PHASE II, MORE TESTING AND MILITARY QUALIFICATION OF SELECTED PART TYPES WILL BE ACCOMPLISHED.
