HI-506, HI-507, HI-508, HI-509
Data Sheet Single 16 and 8/Differential 8-Channel and
4-Channel CMOS Analog Multiplexers
The HI-506/HI-507 and HI-508/HI-509 monolithic CMOS
multiplexers each include an array of sixteen and eight
analog switches respectively, a digital decoder circuit for
channel selection, voltage reference for logic thresholds, and
an enable input for device selection when several
multiplexers are present. The Dielectric Isolation (DI)
process used in fabrication of these devices eliminates the
problem of latchup. DI also offers much lower substrate
leakage and parasitic capacitance than conventional junction
isolated CMOS (see Application Note AN520).

an internal +5V reference, providing a guaranteed minimum
2.4V for logic “1” and maximum 0.8V for logic “0”. This allows
direct interface without pullup resistors to signals from most
logic families: CMOS, TTL, DTL and some PMOS. For
protection against transient overvoltage, the digital inputs
include a series 200пЃ— resistor and diode clamp to each
supply. Replaces DG506A/DG506AA and DG507A/DG507AA The HI-506 is a single 16-channel, the HI-507 is an
8-channel differential, the HI-508 is a single 8-channel and
the HI-509 is a 4-channel differential multiplexer. Selector Switch Replaces DG508A/DG508AA and DG509A/DG509AA Applications Data Acquisition Systems Precision Instrumentation Demultiplexing If input overvoltages are present, the HI-546/HI-547/HI-548/
HI-549 multiplexers are recommended. 1 CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures. …
