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

Protection
The HS-1840ARH, HS-1840AEH, HS-1840BRH and HS-1840BEH
are radiation hardened, monolithic 16 channel multiplexers
constructed with the Intersil Rad-Hard Silicon Gate, bonded wafer,
Dielectric Isolation process. They are 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. Excellent for
use in redundant applications, since the secondary device can be
operated in a standby unpowered mode affording no additional
power drain. More significantly, a very high impedance exists
between the active and inactive devices preventing any interaction.
One of sixteen channel selections 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. The HS-1840ARH, HS-1840AEH,
HS-1840BRH and HS-1840BEH are processed and screened in full
compliance with MIL-PRF-38535 and QML standards. The devices
are available in a 28 Ld SBDIP and a 28 Ld Ceramic Flatpack. …
