Radiation-Hardened 8-Channel Non-Inverting Buffer w/ Dual OE
AF54RHC244
Description
Features & Benefits
Application
The AF54RHC244 is a radiation-hardened-by-design 8-bit non-inverting buffer with 3-state outputs for space, medical imaging, and high-energy physics applications, built on a 180 nm CMOS process with proprietary hardening for resilience to single-event effects and total ionizing dose up to 300 krad(Si). As a member of Apogee Semiconductor’s AF54RHC logic family, it operates from 1.65 V to 5.5 V supply and uses a fully triple-redundant architecture to provide immunity to single-event transients without external redundancy.
- 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 SEL resilient up to LET 80 MeV-cm2/mg
- MEO/GEO Satellites
- Nuclear/Medical Imaging
- Interface
