Radiation Hardened 8 Channel CMOS
Analog Multiplexer with Overvoltage
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.
