POGEE SEMICONDUCTOR AP54RHC301 Radiation Hardened Dual 3-Input Majority Voter with cold sparing Proprietary cold-sparing capability with zero 1 GENERAL DESCRIPTION static power penalty Built-in triple redundancy for enhanced reliabil- The AP54RHC301 is a radiation-hardened by design ity dual 3-Input Majority Voter that is ideally suited for space, medical imaging and other applications de- Internal power-on reset (POR) circuitry ensures manding radiation tolerance and high reliability. It is reliable power up and power down responses fabricated in a 180 nm CMOS process utilizing propri- during hot plug and cold sparing operations etary radiation-hardening techniques, delivering high resiliency to single-event e ects (SEE) and to a total Class 2 ESD protection (4000 V HBM, 500 V CDM) ionizing dose (TID) up to 30 krad (Si). TID resilience of 30krad(Si) This device is a member of the Apogee Semiconductor AP54RHC logic family operating across a voltage supply 2 SEL resilient up to LET of 80MeV-cm /mg range of 1.65Vto5.5V. The AP54RHC301 is an unique discrete majority voter 1.2 LOGIC DIAGRAM logic function that o ers two instances of a triple-input The AP54RHC301 logic function is shown below: voter gate, with individual error outputs. In addition, a dedicated error detected indication is available, in addition to an external error input signal. CC V Zero-power penalty cold-sparing is supported, along 14 with Class 2 ESD protection on all inputs and outputs.
