voltage Protection
Intersil‘s Satellite Applications FlowTM (SAF) devices are fully tested and guaranteed to 100kRAD total dose. This QML Class T device is processed to a standard flow intended to meet the cost and shorter lead-time needs of large volume satellite manufacturers, while maintaining a high level of reliability. The HS-508ARH-T 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, available from the Semiconductor Products Division of Intersil, for further information on the HS-508ARH-T multiplexer in general.
