资 源 简 介
The HS-1840RH/883S is a radiaTIon hardened,monolithic 16 channel mulTIplexer constructed with theIntersil Linear Dielectric IsolaTIon CMOS process. It isdesigned to provide a high input impedance to theanalog source if device power fails (open) or theanalog signal voltage inadvertently exceeds the supplyrails during powered operaTIon. Excellent for use inredundant applications, since the secondary devicecan be operated in a standby unpowered modeaffording no additional power drain. More significantly,a very high impedance exists between the active andinactive devices preventing any interaction. One ofsixteen channel selection is controlled by a 4-bit binaryaddress plus an Enable-Inhibit input which convenientlycontrols the ON/OFF operation of severalmultiplexers in a system. All digital inputs haveelectrostatic discharge protection.The HS-1840RH/883S has been specifically designedto meet exposure to radiation environments. It isavailable in a 28 pin Ceramic Sidebraze dual-in-linepackage and 28 pin Ceramic Flatpack. It is guaranteedoperational from -55oC to +125oC.
