LM393FV-E2

Overview

The LM393FV-E2 is a dual ground-sense comparator manufactured by ROHM Semiconductor, housed in an SSOP-8 surface-mount package. It operates on a single supply voltage ranging from 3 V to 32 V with a typical quiescent current of 600 uA. The device features open-collector outputs capable of sinking up to 16 mA per channel. Key electrical specifications include a maximum input offset voltage of 4.5 mV, a typical input bias current of 50 nA, and a response time of 1 us. The input common-mode voltage range extends from ground to VCC minus 1.5 V, allowing for ground-sensed operation.

Feature Summary

• Ground-sensed input and output capability allows operation with signals referenced to the negative supply rail.
• Open collector output structure enables flexible interfacing with various logic families including TTL, DTL, ECL, MOS, and CMOS.
• Low offset voltage design ensures high precision in voltage comparison applications.
• Wide operating temperature range supports functionality across industrial environments.

Applications

• General purpose voltage monitoring circuits
• Threshold detection systems
• Over-voltage protection circuits

Procurement Notes

Verify component status before procurement as this part may be designated as Not Recommended for New Designs (NRND). Confirm that the SSOP-8 package variant matches your PCB footprint requirements. Ensure compatibility with existing supply chain sources given potential end-of-life implications for new projects.

Selection Notes

Select this component when a dual comparator with ground-referenced inputs is required within a compact SSOP-8 footprint. Consider the 3 V to 32 V supply range and 600 uA current consumption against system power budgets. Verify that the 1 us response time meets the speed requirements of the target application compared to faster alternatives.

Part Context

This device belongs to the LM393 family of dual comparators known for low power consumption and wide supply voltage ranges. The FV suffix specifically denotes the SSOP-8 plastic encapsulation type produced by ROHM Semiconductor. This series is widely utilized in consumer and industrial electronics where space constraints and low cost are critical design factors.

Replacement Considerations

Cross-reference with other LM393 variants such as LM393FVT or LM393FJ for different package options like TSSOP or SOIC. Verify pinout compatibility and electrical parameter equivalence before substituting. Check manufacturer datasheets for any differences in thermal performance or mechanical dimensions between package types.
