Product Overview

The AF54RHC273 is a radiation-hardened by design octal D flip flop that is ideally suited for space, medical imaging and other applications demanding radiation tolerance and high reliability. It is fabricated in a 180 nm CMOS process utilizing proprietary radiationhardening techniques, delivering high resiliency to single-event effects (SEE) and to a total ionizing dose (TID) to 300 krad (Si).

This device is a member of the Apogee Semiconductor AF54RHC logic family operating across a voltage supply range of 1.65 V to 5.5 V.

Zero-power penalty™ cold-sparing is supported, along with Class 2 ESD protection on all inputs and outputs. A proprietary output stage and robust power-on reset (POR) circuit allow the AF54RHC273 to be cold-spared in any redundant configuration with no static power loss on any pad of the device. The redundant output stage also features a high drive capability with low static power loss.

The AF54RHC273 also features a triple-redundant design throughout its entire circuitry, which allows it to be immune to single-event transients (SET) without requiring additional redundant devices.
