Description
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. Specifications for Rad Hard QML devices are controlled by the Defense Logistics Agency Land and Maritime (DLA). The SMD numbers listed here must be used when ordering. Detailed Electrical Specifications for these devices are contained in SMD 5962-96742.

What is the minimum operating supply voltages for HS-508BRH and HS-508BEH?
Question:What is the minimum supply voltages for these parts? Can we use +/-8V? Are you able to make some tests on this component for us? Answer:The minimum supply voltages for these parts is +/-10V. Rds(on) and switching speeds will increase somewhat with the lower supply ...
