LM393FVM-TR

Overview

The LM393FVM-TR is a dual precision voltage comparator manufactured by ROHM Semiconductor. It operates from a single supply of 2V to 36V or split supplies of ±1V to ±18V. The device features very low supply current drain of 0.4mA, independent of supply voltage. Input characteristics include a maximum offset voltage of 2.0mV and low input bias current. The output is open collector, compatible with TTL, DTL, ECL, MOS, and CMOS logic levels.

Feature Summary

• Dual independent precision voltage comparators designed for single or split power supply operation
• Input common-mode voltage range includes ground level even with single supply
• Open collector output allows flexible interfacing with various logic families
• Low power supply current drain remains constant regardless of supply voltage magnitude

Applications

• Limit comparators
• Simple analog to digital converters
• Pulse, squarewave and time delay generators
• Wide range VCO and MOS clock timers
• High voltage digital logic gates

Procurement Notes

Verify the specific suffix FVM-TR against official ROHM documentation to confirm package type and tape-and-reel quantity. Ensure design compliance with the component's electrical limits and operating temperature range before procurement.

Selection Notes

Select this component when ground-sensing capability is required in single-supply systems. The low offset voltage and wide supply range make it suitable for precision applications where power consumption must remain minimal across varying voltage conditions.

Part Context

This part belongs to the LM393 series of dual differential comparators. The series is characterized by its ability to operate directly from a single power supply while maintaining compatibility with standard logic families through its open-collector output structure.

Replacement Considerations

LM393 variants from other manufacturers such as STMicroelectronics or Texas Instruments may serve as functional substitutes if pinout and electrical specifications align with the original design requirements.
