HI-506, HI-507, HI-508, HI-509

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).

The switching threshold for each digital input is established by

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 200

Ω resistor and diode clamp to each

supply.

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.

If input overvoltages are present, the HI-546/HI-547/HI-548/

HI-549 multiplexers are recommended.
