LMV393IDDUR

Overview

The LMV393IDDUR is a quad general-purpose low-voltage comparator manufactured by Texas Instruments. It features four independent comparators in an 16-pin TSSOP package. The device operates from a single supply voltage ranging from 2.7 V to 5.5 V. Key electrical specifications include a maximum propagation delay of 600 ns and a typical input offset voltage of 7 mV. The output stage utilizes open-collector configuration, allowing flexible interfacing with various logic families. It supports a wide operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates four independent high-speed comparators within a single compact package for space-constrained designs.
• Operates efficiently on low single-supply voltages, suitable for battery-powered applications.
• Features open-collector outputs that facilitate direct interface with TTL, CMOS, and other digital logic systems.

Applications

• Overvoltage and undervoltage detection circuits
• Threshold detection and level sensing
• Simple analog-to-digital conversion interfaces

Procurement Notes

Verify the specific suffix 'DDUR' corresponds to the 16-pin TSSOP package and tape-and-reel quantity as defined in the official datasheet. Confirm RoHS compliance status and ensure the ordering part number matches the exact manufacturer designation to avoid substitution errors during procurement.

Selection Notes

Select this component when multiple comparator channels are required in a low-voltage environment. Consider the 600 ns propagation delay for timing-sensitive applications. Ensure the open-collector output requirements align with the system's pull-up resistor strategy and logic voltage levels.

Part Context

This part belongs to the LMV393 family of low-voltage comparators. It provides a quad-channel solution compared to dual-channel variants like the LMV393IDR. The device is designed for cost-effective and space-efficient implementations in portable electronics and industrial control systems requiring simple threshold monitoring.

Replacement Considerations

Check for pin-compatible alternatives such as the LMV339 series or other quad comparators from Texas Instruments. Verify that substitute parts meet the same voltage, speed, and package requirements before implementation.
