Overview

® HS-1840ARH Data Sheet July 27, 2009 FN4355.2 www.DataSheet4U.com Rad-Hard 16 Channel CMOS Analog Multiplexer with High-Z Analog Input Protection The HS-1840ARH is a radiation hardened, monolithic 16 channel multiplexer constructed with the Intersil Rad-Hard Silicon Gate, bonded wafer, Dielectric Isolation process.

It is 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.
