Radiation Hardened 16 Channel CMOS
Analog Multiplexer with High-Z Analog
Input Protection
Intersilâs Satellite Applications FlowTM (SAF) devices are fully
tested and guaranteed to 100kRAD Total Dose. These QML
Class T devices are processed to a standard ï¬ow 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.
Speciï¬cations
Speciï¬cations 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 Speciï¬cations for the HS-1840ARH-T
are contained in SMD 5962-95630. A âhot-linkâ is provided
from our website for downloading.
