HS-1840ARH, HS-1840BRH
Rad-Hard 16 Channel CMOS Analog Multiplexer
with High-Z Analog Input Protection
HS-1840ARH, HS-1840BRH
The HS-1840ARH, HS-1840BRH are radiation hardened,
monolithic 16 channel multiplexers constructed with the
Intersil Rad-Hard Silicon Gate, bonded wafer, Dielectric
Isolation process. They are 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 selections 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, HS-1840BRH are
processed and screened in full compliance with
MIL-PRF-38535 and QML standards. The devices are
available in a 28 Ld SBDIP and a 28 Ld 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.
