5.2 Single-Event Transients (SET)

SETs are defined as heavy-ion-induced transient upsets on output pin 1Q of the SN54SC2T74-SEP. SET testing was performed at room temperature (no external temperature control applied). The species used for the SET testing was 109Ag for a LETEFF = 48MeV × cm2 / mg. Flux of approximately 105 ions / cm2 × s and a fluence of approximately 107 ions / cm2 were used for the SET runs.

Three units were tested across multiple input conditions to determine the worst-case setup for SETs. The unit was tested with VCC of 1.2V, 1.8V, and 5.5V and window trigger of ±1%, ±5%, ±10%, and ±20%. All combinations of VCC and window triggers showed no transient upsets, as listed in Table 5-2

To capture SETs, one NI PXI-5110 scope card was used to continuously monitor the output voltage on pin 1Q. The NI scope was programmed to a sample rate of 100M samples per second (S / s) and recorded 10k samples, with a 20% pretrigger reference, in case of an event (trigger). Under heavy-ions, the SN54SC2T74-SEP did not exhibit any transient upsets
