HI3-0508A-5

Analog Switches, Multiplexers, Demultiplexers Overview

The HI3-0508A-5 is a single 16-channel and 8-channel/differential 8-channel CMOS analog multiplexer manufactured by Intersil. It integrates an array of sixteen analog switches, a digital decoder circuit for channel selection, voltage reference logic thresholds, and an enable input for device selection in multi-device configurations. Fabricated using Dielectric Isolation (DI) process technology, the component eliminates latch-up issues and provides lower substrate leakage and parasitic capacitance compared to conventional junction-isolated CMOS. The device supports a wide analog signal range and features TTL/CMOS compatibility.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Dielectric Isolation (DI) process technology ensures latch-up immunity and reduced substrate leakage.
• Integrated digital decoder circuit simplifies channel selection control.
• Break-before-make switching action prevents momentary short circuits between channels.
• Wide analog signal range accommodates high-voltage applications.

Analog Switches, Multiplexers, Demultiplexers Applications

• Data acquisition systems requiring multi-channel signal routing
• Precision instrumentation involving analog signal switching
• Demultiplexing applications in electronic test equipment

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix designation against official Intersil documentation to confirm RoHS compliance status and pinout configuration. Ensure the ordering code matches the required package type and temperature grade. Cross-reference with Renesas archives as Intersil products are now managed under the Renesas portfolio. Confirm availability through authorized distributors or legacy semiconductor suppliers.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing systems requiring robust analog switching with high isolation and no latch-up risk. The DI process makes it suitable for harsh environments where conventional CMOS might fail. Consider the access time and on-resistance specifications relative to the signal bandwidth requirements. Verify that the supply voltage limits align with the system power rails before integration into the schematic.

Analog Switches, Multiplexers, Demultiplexers Part Context

The HI3-0508A-5 belongs to the HI-506/HI-507 and HI-508/HI-509 family of monolithic CMOS multiplexers. These devices were originally designed to replace Harris DG506A/DG506AA and DG508A/DG508AA series components. The product line represents a transition from older junction-isolated technologies to more reliable dielectric isolation methods, offering improved performance metrics for industrial and commercial data acquisition applications.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Officially documented replacements include the DG506A, DG506AA, DG507A, DG507AA, DG508A, DG508AA, DG509A, and DG509AA. Verify pin compatibility and electrical parameter equivalence before substituting these legacy Harris components with the HI3-0508A-5 in existing designs.
