HS-1840ARH
Data Sheet
August 1999
File Number 4355.1
Rad-Hard 16 Channel CMOS Analog
Multiplexer with High-Z Analog Input
Protection
Features
• Electrically Screened to SMD # 5962-95630
• QML Qualified per MIL-PRF-38535 Requirements
• Pin-to-Pin for Intersil’s HS-1840RH and HS-1840/883S
• Improved Radiation Performance
The HS-1840ARH is a radiation hardened, monolithic 16
channel multiplexer constructed with the Intersil Rad-Hard
Silicon Gate, bonded wafer, 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.
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 selection 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.
