Rochester Electronics, an aftermarket supplier of integrated circuits, has purchased National Semiconductor Corp.'s space-level logic radiation-hardened inventory.

With nearly 300 specific part numbers in total, the purchase includes the 1003XX ECL, 54LS, 54F, 54AC, 54ACT, and 54ACTQ microcircuit families. Terms of the agreement were not disclosed, but the purchase included all residual finished goods and wafers, and all the required supporting documentation, such as SEM, wafer lot acceptance, radiation, and X-ray reports. Rochester Electronics is a Qualified Manufacturers List (QML) manufacturer and was approved for Class V by Defense Supply Center, Columbus (DSCC), in May 2007. At that time, DSCC also approved Fairchild's wafer-manufacturing site in South Portland, Maine, for Rochester Electronics QML products. This is the same location that previously made space-level logic wafers for National Semiconductor. Rochester Electronics has a current wafer fabrication contract with Fairchild and will be building additional space-level wafers in order to provide long-term support for space-level and rad-hard logic products.
