HI3-0508-5

Analog Switches, Multiplexers, Demultiplexers Overview

The HI3-0508-5 is a single-channel CMOS analog multiplexer manufactured by Harris Corporation. It integrates an array of sixteen analog switches, a digital decoder circuit for channel selection, a voltage reference for logic thresholds, and an enable input for device selection in multi-device configurations. The component utilizes Dielectric Isolation (DI) processing to eliminate latch-up issues and reduce substrate leakage and parasitic capacitance compared to conventional junction-isolated CMOS technologies.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the manufacturer origin as Harris Corporation or Intersil Corporation, noting that Intersil acquired Harris Semiconductor assets. Confirm RoHS compliance status if lead-free availability is required for the specific procurement batch. Ensure the package type matches the system design requirements for the sixteen-channel configuration.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a high-channel-count multiplexer with low parasitic capacitance is required. The Dielectric Isolation process makes it suitable for applications demanding high reliability without latch-up risks. Verify that the ±15V analog signal range and 180Ω ON resistance meet the specific circuit performance criteria.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the HI-506/HI-507 and HI-508/HI-509 family of monolithic CMOS multiplexers. It serves as a replacement for the DG508A/DG508AA series devices. The family shares common fabrication techniques focused on eliminating latch-up through dielectric isolation, providing a robust solution for analog signal routing in mixed-signal environments.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly documented direct replacements include the DG508A and DG508AA models. Designers should verify pin compatibility and electrical parameter alignment before substituting these legacy junction-isolated parts with the dielectric-isolated HI3-0508-5.
