July 1999 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. Features 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 п‚±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. Improved rDS(ON) Linearity QML Class T, Per MIL-PRF-38535 Radiation Performance
