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 Application Notes 520 and 521 for further information on the HS-508BRH, HS-508BEH multiplexers in general. The HS-508BRH, HS-508BEH have been specifically designed to meet exposure to radiation environments. Operation from -55°C to +125°C is guaranteed.
