The purpose of this study was to characterize the effects of heavy-ion irradiation on the single-event latch-up (SEL) performance of the TLV1H103-SEP 5.5V, high speed comparator. Heavy-ions with an LETEFF of 48.47MeV-cm2/mg were used to irradiate the device with a fluence of 1 × 107 ions/cm2. The results demonstrate that the TLV1H103-SEP is SEL-immune up to LETEFF = 43MeV-cm2/mg at 125°C.
Characterization of single-event transients (SET) was also performed, up to a surface LETEFF = 50MeV-cm2 / mg at 125°C.

The TLV1H103-SEP is a 325MHz, high-speed comparator with rail-to-rail inputs and a propagation delay of 2.5ns. The combination of fast response and wide operating voltage range make the comparators suitable for narrow signal pulse detection and data and clock recovery applications in LIDAR, range finders, and line receivers.
