HI3-0508-5Z

Analog Switches, Multiplexers, Demultiplexers Overview

The HI3-0508-5Z is a single 8-to-1 analog multiplexer manufactured by Intersil, now part of Renesas Electronics. It features a monolithic CMOS construction with an integrated digital decoder for channel selection and an enable input. The device operates within a supply voltage range of ±10V and supports a transition time of up to 1.2µs. It utilizes Dielectric Isolation (DI) technology to eliminate latchup issues and reduce substrate leakage. The component is housed in a 28-pin PDIP package with through-hole mounting, suitable for industrial environments operating between -40°C and +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Dielectric Isolation (DI) process eliminates latchup and reduces parasitic capacitance
• Integrated digital decoder circuit for direct channel selection
• Internal voltage reference establishes logic thresholds without external pull-up resistors
• Digital inputs protected against transient overvoltage via series resistors and diode clamps

Analog Switches, Multiplexers, Demultiplexers Applications

• Harsh environment data acquisition systems requiring MIL-STD-883 Class Q qualification
• Industrial instrumentation involving multiple analog signal sources
• Test and measurement equipment requiring high-reliability analog switching

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the manufacturer designation carefully, as this component originates from Intersil before its acquisition by Renesas. Confirm that the specific suffix '5Z' aligns with the required commercial temperature range (-40°C to +85°C) and PDIP packaging. Ensure procurement channels provide traceability to the original Intersil specifications or current Renesas documentation to guarantee authenticity and compliance with the stated electrical characteristics.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a ruggedized, single 8-channel analog switch is required for harsh environments. The DI process makes it superior to standard junction-isolated CMOS for applications sensitive to latchup. Compare against the HI-509 if differential switching is needed instead of single-ended. Verify that the ±10V supply capability and 1.2µs transition time meet the system's speed and power constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the HI-506/HI-507/HI-508/HI-509 family of monolithic CMOS multiplexers. The HI-508 specifically denotes the single 8-channel configuration. These devices are characterized by their robust Dielectric Isolation fabrication, which distinguishes them from conventional CMOS alternatives by offering lower leakage and higher reliability in demanding operational conditions.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The JM38510/19007BEA is the JAN version of the HI-508, offering equivalent functionality with military-grade qualification. For non-military replacements, verify compatibility with other HI-508 variants or similar 8-channel CMOS multiplexers, ensuring pinout and electrical parameters match.
