TR014 SEE IS-1825ASRH

The IS-1825AS was found to be immune to damaging SEE when run at VCC = 20V and 24V, a case temperature of +125°C ±10°C, and irradiated with normal incidence gold ions for a surface LET of 86.3MeV•cm2/mg. Four parts irradiated to 1x107ion/cm2 each showed no significant changes in the four monitor. The IS-1825AS was found to have significant output pulse width disturbance due to ion irradiation. At the four LET levels tested (86.3, 42.8, 28.3, and 19.9MeV•cm2/mg) while the other output had a double pulse event. In addition to the output SET described above, three of four parts showed a susceptibility to soft-start cycling SEFI when irradiated with gold for LET = 86.3MeV•cm2/mg. SEFI events were also seen for one of four parts when irradiated with silver for LET = 42.8MeV•cm3/mg.
