HI-546, HI-547,
HI-548, HI-549
Description
August 1997
Single 16 and 8, Differential 8-Channel and 4-Channel
CMOS Analog MUXs with Active Overvoltage Protection
Features
• Analog Overvoltage Protection . . . . . 70V
P-P
The HI-546, HI-547, HI-548 and HI-549 are analog multiplexers with
active overvoltage protection and guaranteed r
ON
matching. Analog input
• No Channel Interaction During Overvoltage
levels may greatly exceed either power supply without damaging the
device or disturbing the signal path of other channels. Active protection
• Guaranteed r

Matching
circuitry assures that signal fidelity is maintained even under fault condi-
tions that would destroy other multiplexers.
• 44V Maximum Power Supply
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

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
• Standby Power (Typical) . . . . . . . . . .7.5mW
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,
Applications
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 fur-
ther information see Application Notes AN520 and AN521. The HI-546 and

Ceramic LCC package. The HI-548/549 devices are available in a 16 lead
Plastic or Ceramic DIP and a 20 pad Ceramic LCC package.
• Break-Before-Make Switching
The HI-546, HI-547, HI-548 and HI-549 are offered in industrial/commercial
and military grades. Additional Hi-Rel screening including 160 hour Burn-In is
specified by the “-8” suffix. For MIL-STD-883 compliant parts, request the
HI-546/883, HI-547/883, HI-548/883 and HI-549/883 datasheets.
