TLC339MD

Comparators Overview

The TLC339MD is a quad micropower comparator manufactured by Texas Instruments, belonging to the LinCMOS family. It integrates four independent high-gain comparators within a single 14-pin SOIC package. The device operates on a single supply voltage ranging from 3V to 16V or dual supplies of ±1.5V to ±8V. Key electrical characteristics include a maximum input offset voltage of 5mV and a typical quiescent current of 11µA per channel. It features an open-drain output configuration suitable for wired-OR connections.

Comparators Feature Summary

• LinCMOS technology ensures extremely low power consumption
• Wide single-supply operating voltage range
• Open-drain outputs allow flexible logic interfacing

Comparators Applications

• Battery-powered portable equipment
• Threshold detection circuits
• Simple time delay generation
• On-off temperature control systems

Comparators Procurement Notes

Verify the specific suffix 'MD' against the official Texas Instruments datasheet to confirm package type and temperature grade. Ensure the component matches the standard TLC339 specifications regarding pinout and electrical limits before integration into the design.

Comparators Selection Notes

Select this component when low static power dissipation is critical compared to bipolar comparators. The wide supply voltage range makes it suitable for direct battery operation without complex regulation. Consider the open-drain output requirement for pull-up resistor implementation in the circuit design.

Comparators Part Context

This part belongs to the TLC339 series, which represents a CMOS version of the industry-standard LM339. The LinCMOS process provides superior power efficiency while maintaining comparable performance metrics. It serves as a drop-in replacement for legacy designs requiring lower quiescent current.

Comparators Replacement Considerations

Official substitutes include the LM339 series for bipolar equivalents and other TLC339 variants with different packaging options such as TLC339IDR or TLC339CPWR, provided the pinout remains compatible.
