Abstract : The high-power logic circuits (RSN54H00 series) has been quoted to function within nominal data sheet specifications at a neutron fluence of 5 x 10 to the 14th power n/sq cm (E > 10 keV). To determine the degradation beyond this point and how it would restrict circuit performance, two Motorola 54H79 Dual-D Flip-Flop samples were tested to a total fluence of 1.9 x 10 to the 15th power n/sq cm (E > 10 keV). The tests were performed at the the White Sands Missile Range Fast-Burst Reactor (WSMRFBR). The report presents the results of this test. The 54H79 can be considered representative for the whole 54H00 family.
