Introducing the Majority Voter: New radiation migitation solution from 3D PLUS
3D PLUS introduces with the Majority Voter a new cutting-edge radiation mitigation solution. The Majority Voter (3DRC3508ES2861) is a 3-input, high-speed octal majority voter module with built-in triple redundancy designed for space environments where reliability is paramount.
The Majority Voter (3DRC3508ES2861) is a 3-input, high-speed octal majority voter module with built-in triple redundancy. With the three 8-bit inputs used for majority voting, the module provides the result of the vote as an output, along with an error signal indicating if there is a difference between any of the input bits (also 8-bit), providing an extra layer of reliability of the module.
The module operates from a supply voltage range of 1.65 V to 5.5 V and, thanks to the cold protection function, can be used in any type of redundancy configuration, making it suitable for a wide range of applications.
Key features
- 1.65V to 5.5V voltage supply
- Input voltage up to 5.5V at any Vcc
- Provides logic-level down translation to Vcc
- Cold sparing capability
- Internal power-on reset (POR) circuitry
- 13ns maximum propagation delay at 3.3V
- Temperature Range -55°C / +125°C
Radiation Tolerance
- TID > 30 krad(Si)
- SEL LETth > 74.7 MeV.cm²/mg at +125°C
- SET LETth > 74.7 MeV.cm²/mg at +125°C
Applications
- Mitigating SEE effects on non SEE-immune device.
- TMR on any digital system signal.
The Majority Volter module is immune to Single Event Transients (SET) and Single Event Latchup (SEL) by design, and insensitive to Single Event Upsets (SEU) and Multiple Bit Upsets (MBU) by process (CMOS IC), qualifying its use in space environment. Its integration into digital systems improves reliability through the use of the Triple Modular Redundancy (TMR). Notably, the space-qualified majority voter module is ITAR-free.
