Protection

The HS-508ARH 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,whicheliminatesthepossibilityofdamagewhen
supplies are off, but input signals are present. Equally
important, it can withstand brief input transient spikes of
severalhundredvolts; whichotherwisewouldrequirecomplex
external protection networks. Necessarily, ON resistance is
somewhat higher than similar unprotected devices, but very
low leakage current combine to produce low errors.

Semiconductor Products Division of Intersil, for further
information on the HS-508ARH multiplex er in gener al.
