August 1999 File Number 4355.1
Rad-Hard 16 Channel CMOS Analog
Multiplexer with High-Z Analog Input
Protection
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.
The HS-1840ARH is processed and screened in full compliance
with MIL-PRF-38535 and QML standards. The device is
available in a 28 lead SBDIP and a 28 lead Ceramic Flatpack.
Specifications for Rad Hard QML devices are controlled
by the Defense Supply Center in Columbus (DSCC). The
SMD numbers listed here must be used when ordering.
Detailed Electrical Specifications for these devices are
contained in SMD 5962-95630. A “hot-link” is provided
on our homepage for downloading.
