HS-0546RH, HS-0547RH
Data Sheet

File Number
3544.2
Radiation Hardened Single 16/Differential
8 Channel CMOS Analog Multiplexers with
Active Overvoltage Protection
The HS-0546RH and HS-0547RH are radiation hardened
analog multiplexers with Active Overvoltage Protection and
guaranteed r
ON
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-0546RH and
HS-0547RH 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-0546 is a 16 channel
device and the HS-0547 is an 8 channel differential version. If
input overvoltage protection is not needed, the HS-0506 and
HS-0507 multiplexers are recommended.
