DATASHEET
HI-548/883, HI-549/883
Single 8/Differential 4-Channel CMOS Analog Multiplexers with
Active Overvoltage Protection
The HI-548/883 and HI-549/883 are 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
P-P
levels with ±15V
supplies. Digital inputs will also 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 HI-548/883 and
HI-549/883 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 HI-548/883 is an 8-channel
device, and the HI-549/883 is a 4-channel differential version.
If input overvoltage protection is not needed, the HI-508/883
and HI-509/883 multiplexers are recommended. For further
information see Application Note
AN520.
