Apogee Semiconductor AP54RHC301 Rad-Hard Dual 3-Input Majority Voters
Apogee Semiconductor AP54RHC301 Rad-Hard Dual 3-Input Majority Voters are designed for space, medical imaging, and other applications requiring radiation tolerance and high reliability. The radiation-hardened by design AP54RHC301 Dual 3-Input Majority Voters are fabricated in a 180nm CMOS process. These voters deliver high resiliency to single-event effects (SEE) and to a total ionizing dose (TID) up to 30krad (Si). The AP54RHC301 is available in an SMD TSSOP-14 package with an extended operating temperature range of -55°C to 125°C. These voters are designed for space, medical imaging, and other radiation tolerance applications.The AP54RHC301 Rad-Hard Dual 3-Input Majority Voters are part of the AP54RHC logic family operating across a voltage supply range of 1.65VDC to 5.5VDC. These voters support zero-power penalty™, cold-sparing, and Class 2 ESD protection on all inputs and outputs. A proprietary output stage and full power-on reset (POR) circuit allow the AP54RHC301 to be cold-spared in any redundant configuration with no static power loss on any device pad.
Rad-Hard Overview
Apogee Semiconductor creates Radiation Hardened (Rad-Hard) semiconductor devices for Rad-Hard and extreme Single Event Effects (SEE, SET, SEU, SEL) fields; from Space (QML-V, QML-S) to MEO, LaGrange, LEO, Atmospheric to Downhole applications. These devices are also compatible with all aerospace, defense, military, and naval applications having a full Mil-Temp range of -55°C to +125°C. Apogee is a turnkey mixed-signal ASIC (MS-ASIC) capable firm with secure capabilities, and all Apogee products can be produced with ITAR and CONUS flows.
