Description
The HS-201HSRH and HS-201HSEH are monolithic BiCMOS analog switches featuring power-off high input impedance, very fast switching speeds and low ON-resistance. Fabrication on our DI RSG process ensures SEL immunity and only very slight low dose rate sensitivity (ELDRS). These Class V/Q devices are tested and guaranteed for 300krad(Si) total dose performance. Power-off high input impedance enables the use of this device in redundant circuits without causing data bus signal degradation. ESD protection, overvoltage protection, fast switching times, low ON-resistance, and guaranteed radiation hardness make the HS-201HSRH ideal for any space application that requires improved switching performance.

What is the minimum operating supply voltages for HS-201HSEH and HS-201HSRH?
Question:Can I use this switch with power supplies at +/-5V or +/-8V instead of the minimum recommended +/-10V? Answer:We do not recommend operating this part with supply voltages less than +/-10V. The part may not switch with supply voltages below +/-10V.

Are the HS-201 rad hard analog switches inputs and outputs interchangeable?
The preferred and safest way is the signal needs to be connected to the Sx input and the load connected to the Dx output of the SPST switch. Each of the SPST switches have over-voltage protection and power off high impedance circuitry on the Sx inputs. When the part ...
