Sensor And Detector Interfaces Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and environmental compliance. Ensure that the selected variant matches the required lead-free status and packaging format for the intended manufacturing process. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity before procurement.

Sensor And Detector Interfaces Selection Notes

Select this component for applications requiring low quiescent current operation and integrated drive capabilities for piezoelectric sounders. Consider the wide operating voltage range and the inclusion of an LED driver when designing compact alarm systems. Evaluate the thermal performance and absolute maximum ratings to ensure reliable operation within the specified temperature range.

Sensor And Detector Interfaces Part Context

The RE46C101 belongs to the R&E International product line, now a subsidiary of Microchip Technology. This series focuses on specialized driver circuits for acoustic and visual signaling components. The S8TF suffix typically denotes an 8-pin SOIC package with tape and reel packaging, distinguishing it from DIP or tube variants within the same functional family.

Sensor And Detector Interfaces Replacement Considerations

Direct replacements may include other RE46C101 variants with different packaging options such as the RE46C101S8F (tube) or RE46C101E8F (DIP). Verify pin compatibility and electrical characteristics before substituting. Consult the datasheet for any functional differences between packaging types.
