| HS-1840ARH-T TM Data Sheet July 1999 FN4589.1 Radiation Hardened 16 Channel CMOS Analog Multiplexer with High-Z Analog Input Protection Intersil's Satellite Applications FlowTM (SAF) devices are fully tested and guaranteed to 100kRAD Total Dose. These QML Class T devices are processed to a standard flow intended to meet the cost and shorter lead-time needs of large volume satellite manufacturers, while maintaining a high level of reliability. The HS-1840ARH-T is a Radiation Hardened, monolithic 16 channel multiplexer constructed with the Intersil Rad-Hard Silicon Gate, 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. Selection of one of sixteen channels 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 inputs have electrostatic discharge protection.
