FN4824.2
Radiation Hardened 8 Channel CMOS
Analog Multiplexer with Overvoltage
Protection
The HS-508BRH is a dielectrically isolated, radiation
hardened, CMOS analog multiplexer incorporating an
important feature; it withstands 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, it 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 Application Notes 520 and 521 for further
information on the HS-508BRH multiplexer in general.
The HS-508BRH has been specifically designed to meet
exposure to radiation environments. Operation from -55°C to
+125°C is guaranteed.
