Overview
The MUX24EP is an obsolete analog multiplexer manufactured by Analog Devices Inc. It features a dual configuration comprising one eight-channel and one four-channel JFET switch array within a single package. The device utilizes JFET technology to provide high input impedance and low leakage current characteristics suitable for precision signal routing. It supports overvoltage protection on the inputs, allowing signals exceeding the supply rails to be handled without damage. The component is designed for applications requiring reliable switching of analog signals with minimal distortion.
Feature Summary
- Dual architecture integrating an eight-channel and a four-channel JFET multiplexer in a single unit
- JFET input stage providing high input impedance and low off-state leakage current
- Integrated overvoltage protection capability on input channels
- Designed for precision analog signal routing and switching applications
Applications
- Precision data acquisition systems requiring multi-channel signal selection
- Industrial instrumentation involving isolated sensor signal routing
- Test and measurement equipment needing high-impedance analog switching
- Medical diagnostic devices utilizing precise analog signal paths
Procurement Notes
Verify manufacturing status carefully as this part is listed as obsolete or discontinued by major distributors. Confirm availability through authorized channels or secondary markets if production is halted. Ensure that any sourced units are genuine components from Analog Devices Inc. and not counterfeits. Check datasheet revisions for any specific handling requirements associated with legacy JFET multiplexers before integration into new designs.
Selection Notes
Select this component only when a combined eight-and-four-channel JFET multiplexer is required in a single footprint. Consider the JFET technology benefits for high-impedance sources versus CMOS alternatives. Evaluate the overvoltage protection needs against system signal ranges. Since the part is obsolete, assess long-term supply chain risks and potential need for design refreshes using modern equivalents.
Part Context
The MUX24EP belongs to the family of JFET analog multiplexers produced by Analog Devices Inc. (formerly Maxim Integrated). These devices are characterized by their use of junction field-effect transistors for the switching elements, offering superior performance in terms of leakage and input impedance compared to standard CMOS switches. This specific model combines two different channel counts to reduce board space in complex signal conditioning circuits.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. As the MUX24EP is marked as obsolete, engineers must identify alternative JFET multiplexers with similar channel configurations and electrical specifications. Consult Analog Devices technical support or distributor catalogs for current generation replacements that match the functional requirements.
