HS-1840ARH-T
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.
Specifications
Specifications for Rad Hard QML devices are controlled by
the Defense Supply Center in Columbus (DSCC). The SMD
numbers listed below must be used when ordering.
Detailed Electrical Specifications for the HS-1840ARH-T
are contained in SMD 5962-95630. For more information,

Intersil’s Quality Management Plan (QM Plan), listing all
Class T screening operations, is also available on our
website.
