Description
The HS-1840RH/883S is a radiation hardened,
monolithic 16 channel multiplexer constructed with the
Intersil Linear Dielectric Isolation CMOS 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
rails during powered operation. 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 conve-
niently controls the ON/OFF operation of several
multiplexers in a system. All digital inputs have
electrostatic discharge protection.
The HS-1840RH/883S has been specifically designed
to meet exposure to radiation environments. It is
available in a 28 pin Ceramic Sidebraze dual-in-line
package and 28 pin Ceramic Flatpack. It is guaranteed
operational from -55
o
C to +125
o
C.
