Description
The HS-1840ARH is a radiation hardened, monolithic 16
channel multiplexer constructed with the Harris 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 volt-
age inadvertently exceeds the supply by up to ±35V, regard-
less 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 imped-
ance exists between the active and inactive devices prevent-
ing 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.
Detailed Electrical Specifications are contained in DSCC
SMD Number 5962-95630.
