Overview
The MUX28ET is a monolithic analog multiplexer manufactured by Analog Devices Inc., configured as a double pole, 8-position electronic switch array with an additional OFF position. It utilizes JFET technology to provide overvoltage protection for the inputs. The device is housed in a 28-CDIP package and supports through-hole mounting. It operates within a temperature range of -25°C to +85°C.
Feature Summary
- Monolithic construction integrating eight differential channels into a single unit
- JFET input architecture providing inherent overvoltage protection capabilities
- Double pole, 8-position configuration with dedicated OFF state
Applications
- Data acquisition systems requiring signal routing
- Industrial process control instrumentation
- Test and measurement equipment
Procurement Notes
Verify component authenticity due to obsolete status. Confirm package integrity and pin compatibility during sourcing. Check for RoHS compliance variations across production batches. Ensure storage conditions prevent moisture damage prior to installation.
Selection Notes
Evaluate channel count requirements against alternative multiplexers. Consider JFET input characteristics for high-impedance source applications. Assess thermal performance within the specified operating range. Verify mechanical fit for the 28-CDIP footprint in existing designs.
Part Context
This component belongs to the MUX-28 family of analog switches. It serves as a legacy solution for multi-channel signal switching. The ET suffix denotes specific packaging and processing details. It complements other interface devices in data conversion chains.
Replacement Considerations
The MUX28ET is listed as obsolete. Source equivalent parts from authorized distributors only. Validate pinout compatibility before substitution. Review datasheet specifications for functional equivalence.
