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.
Feature Summary
- Dielectric Isolation process eliminates latch-up problems and reduces substrate leakage
- Break-before-make switching action prevents signal shorting during channel transitions
- TTL and CMOS compatible logic interfaces for versatile application integration
Applications
- Data acquisition systems
- Precision instrumentation
- Demultiplexing applications
- Selector switch circuits
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.
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.
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.
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.
