Product Overview
The AF54RHC04 is a radiation-hardened by design hex inverter 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 radiation-hardening techniques, delivering high resiliency to single–event effects (SEE) and to a total ionizing dose (TID) up 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 PENATLY™ 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 AF54RHC04 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 AF54RHC04 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.
This device provides six instances of the Boolean logical function INVERTER (Y = Ā)..
- 1.65 VDC to 5 VDC operation
- Inputs tolerant up to 5.5 VDC at any VCC
- Provides logic-level down translation to VCC
- Extended operating temperature range (-55°C to +125°C)
- Proprietary cold-sparing capability with zero static power penalty
- Built-in triple redundancy for enhanced reliability
- Internal low-loss power-on reset (POR) circuitry ensures reliable power up and power down responses during hot plug and cold sparing operations
- Class 2 ESD protection (4000 V HBM, 500 V CDM)
- TID resilience of 30 krad (Si) or 300 krad (Si)
- SEL resilient up to LET 80 MeV-cm2/mg
- MEO/GEO Constellations
- Deep Space Exploration
- Glue Logic
