HI-506A, HI-507A, HI-508A, HI-509A
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 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 1k 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 Note AN520.

NOTES:
1. These Intersil Pb-free plastic packaged products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte
tin plate PLUS ANNEAL - e3 termination finish, which is 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.
2. Pb-free PDIPs can be used for through hole wave solder processing only. They are not intended for use in Reflow solder processing applications.
