The HS-0548RH and HS-0549RH are radiation hardened
analog multiplexers with Active Overvoltage Protection and
guaranteed rON matching. Analog input levels may greatly
exceed either power supply without damaging the device or
disturbing the signal path of other channels. Active
protection circuitry assures that signal fidelity is maintained
even under fault conditions that would destroy other
multiplexers. Analog inputs can withstand constant 70V
peak-to-peak levels with ±15V supplies and digital inputs will
sustain continuous faults up to 4V greater than either supply.
In addition, signal sources are protected from short circuiting
should multiplexer supply loss occur: each input presents
1kΩ of resistance under this condition. These features make
the HS-0548RH and HS-0549RH ideal for use in systems
where the analog inputs originate from external equipment
or separately powered circuitry. Both devices are fabricated
with 44V dielectrically isolated CMOS technology. The
HS-0548 is an 8 channel device and the HS-0549 is a
4 channel differential version. If input overvoltage protection
is not needed, the HS-0508 and HS-509 multiplexers are
recommended.
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 5962-95694. A “hot-link” is provided
on our homepage for downloading.
