Radiation Hardened 16 Channel CMOS
Analog Multiplexer with High-Z Analog
Input Protection
Intersil鈥檚 Satellite Applications Flow
TM
(SAF) devices are fully
tested and guaranteed to 100kRAD Total Dose. These QML
Class T devices are processed to a standard 鏗俹w 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
鹵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.
