Single 16 and 8, Differential 8-Channel
and 4-Channel CMOS Analog MUXs with
Active Overvoltage Protection
The HI-546, HI-547, HI-548 and HI-549 are analog
multiplexers with active overvoltage protection and
guaranteed r
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
±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-546, HI-547, HI-548 and HI-549 ideal for use in systems
where the analog inputs originate from external equipment
or separately powered circuitry. All devices are fabricated
with 44V Dielectrically Isolated CMOS technology. The
HI-546 is a single 16-Channel, the HI-547 is an 8-Channel
differential, the HI-548 is a single 8-Channel and the HI-549
is a 4-Channel differential device. If input overvoltage
protection is not needed the HI-506/507/508/509
multiplexers are recommended. For further information see
Application Notes AN520 and AN521.

*Pb-free PDIPs can be used for through hole wave solder processing
only. They are not intended for use in Reflow solder processing
applications.
**Add “96” suffix for tape and reel.
NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.
