LM393TLX

Overview

The LM393TLX is a dual precision voltage comparator manufactured by Texas Instruments, packaged in an 8-pin TSSOP (μSMD) format. It features two independent comparators with open-collector outputs and a wide single-supply voltage range of 2V to 28V. The device exhibits a typical response time of 1.3µs and operates within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Dual independent precision voltage comparators integrated into a compact surface-mount package
• Open-collector output configuration compatible with various logic families including TTL and CMOS
• Wide single-supply operating voltage range enabling direct sensing near ground potential

Applications

• Limit comparators for threshold detection
• Simple analog-to-digital conversion circuits
• Pulse, squarewave, and time delay generators

Procurement Notes

Verify the specific suffix 'TLX' against the official Texas Instruments datasheet to confirm it denotes the standard LM393 variant in TSSOP-8 packaging. Ensure the component matches the required commercial temperature grade and pinout compatibility before integration into designs requiring precise offset voltage specifications.

Selection Notes

Select this component when a low-cost, dual-channel comparator is needed for single-supply applications. It is suitable for designs requiring open-collector outputs that interface directly with digital logic systems. Consider the TSSOP package size constraints and the specific response time requirements relative to other high-speed comparator alternatives.

Part Context

This part belongs to the LMx93 family of dual differential comparators from Texas Instruments. These devices are designed specifically for operation from a single power supply over a wide range of voltages, offering low power supply current drain independent of the supply voltage magnitude.

Replacement Considerations

LM393DR: Standard SOIC-8 version of the same comparator. LM2903: Industrial temperature grade equivalent with extended operating range.
