Data Sheet
HI-506A, HI-507A, HI-508A, HI-509A
June 1999 File Number 3143.2
16-Channel, 8-Channel, Differential
8-Channel and Differential 4-Channel,
CMOS Analog MUXs with Active
Overvoltage Protection
The HI-506A, HI-507A, HI-508A and HI-509A are analog
multiplexers with active overvoltage protection. 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 70VP-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-506A, HI-507A, HI-508A and HI-509A
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-506A is a single 16-Channel multiplexer,
the HI-507A is an 8-Channel differential multiplexer, the
HI-508A is a single 8-Channel multiplexer and the HI-509A is
a differential 4-Channel multiplexer. 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.
