HS-508BEH

Radiation Hardened 8 Channel CMOS Analog Multiplexers with Overvoltage Protection HS-508BRH, HS-508BEH 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.
