Rad-Hard 16 Channel BiCMOS Analog Multiplexer with High-Z Analog Input Protection

The HS-1840ARH, HS-1840AEH, HS-1840BRH and HS-1840BEH are radiation hardened, monolithic 16 channel multiplexers constructed with the Intersil Rad-Hard Silicon Gate, bonded wafer, Dielectric Isolation process. They are designed to provide a high input impedance to the analog source if device power fails (open), or the analog signal voltage inadvertently exceeds the supply by up to ±35V, regardless of whether the device is powered on or off. Excellent for use in redundant applications, since the secondary device can be operated in a standby unpowered mode affording no additional power drain. More significantly, a very high impedance exists between the active and inactive devices preventing any interaction.
