HS9-508BRH-8

® HS-508BRH Data Sheet January 2001 FN4824.1 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 -55oC to 125oC is guaranteed.
