HS-508BRH

Radiation Hardened 8 Channel CMOS

Analog Multiplexer with Overvoltage

Protection

The HS-508BRH 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 for further

information on the HS-508BRH multiplexer in general.

The HS-508BRH has been specifically designed to meet

exposure to radiation environments. Operation from -55°C to

+125°C is guaranteed.
