November 17, 2011 Radiation Hardened 8 Channel CMOS Analog Multiplexers with Overvoltage
Protection
The HS-508BRH, HS-508BEH are dielectrically isolated,
radiation hardened, CMOS analog multiplexers incorporating an
important feature; they withstand analog input voltages much
greater than the supplies. This is essential in any system where
the analog inputs originate outside the equipment. They can
withstand a continuous input up to 10V greater than either
supply, which eliminates the possibility of damage when
supplies are off, but input signals are present. Equally
important, they can withstand brief input transient spikes of
several hundred volts; which otherwise would require complex
external protection networks. Necessarily, ON resistance is
somewhat higher than similar unprotected devices, but very low
leakage current combine to produce low errors. Reference

HS-508BRH, HS-508BEH multiplexers in general.
The HS-508BRH, HS-508BEH have been specifically designed
to meet exposure to radiation environments. Operation from
-55В°C to +125В°C is guaranteed. Features Electrically Screened to SMD # 5962-96742 QML Qualified per MIL-PRF-38535 Requirements Radiation Environment …
