The LMX1860-SEP is a radiation-hardened device in a plastic package which allows these devices to be used in space applications. The device was verified immune to 43MeV × cm² / mg at 125°C for Single-Event Latch-up (SEL) and Single-Event Functional Interrupt (SEFI). Each fabrication lot was tested according to MIL-STD-883 for Radiation Lot Acceptance Tested (RLAT) up to 30 krad(Si) and each assembly and test lot follows the process flow shown in Figure 2-1. To verify the quality of the LMX1860-SEP, the device is qualified with Space EP requirements. See Section 3 for further details.
