HS-1840RH

The HS-1840RH/883S is a radiation hardened, monolithic 16 channel multiplexer constructed with the Intersil Linear Dielectric Isolation CMOS 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 rails during powered operation. HS-1840RH is 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. One of sixteen channel selection is controlled by a 4-bit binary address plus an Enable-Inhibit input which conveniently controls the ON/OFF operation of several multiplexers in a system. All digital inputs have electrostatic discharge protection.

The HS-1840RH/883S has been specifically designed to meet exposure to radiation environments. It is available in a 28 pin Ceramic Sidebraze dual-in-line package and 28 pin Ceramic Flatpack. It is guaranteed operational from -55 to +125.
