AP54RHC288 Radiation Hardened Dual-Input Arbiters

Apogee Semiconductor AP54RHC288 Radiation Hardened Dual-Input Arbiters are members of the AP54RHC logic family, operating across a voltage supply range of 1.65V to 5.5V. These two-channel dual-input arbiters deliver high resiliency to Single-Event Effects (SEE) and 30krad (Si) Total Ionizing Dose (TID). The AP54RHC288 arbiters feature an internal Power-On Reset (POR) circuit that ensures reliable power-up and power-down responses during hot plug and cold-sparing operations. These arbiters include a triple-redundant design throughout the circuit, which allows the devices to be immune to Single-Event Transients (SET). The AP54RHC288ALT-R arbiters are flight-A grade, and AP54RHC288ELT-R are evaluation grade. These arbiters are used in Low Earth Orbit (LEO) constellations, small satellites, and medical imaging.
