Description
The HS-1840RH is a radiation hardened, monolithic 16
channel multiplexer constructed with the Harris 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 conveniently controls the ON/OFF
operation of several multiplexers in a system. All digital
inputs have electrostatic discharge protection.
The HS-1840RH has been specifically designed to meet
exposure to radiation environments. It is available in a 28
lead Ceramic Sidebraze dual-in-line package and 28 lead
Ceramic Flatpack. It is guaranteed operational from -55^oC to
+125^oC.
