TLC339CDBR

Comparators Overview

The TLC339CDBR is a quad comparator integrated circuit manufactured by Texas Instruments, belonging to the LinCMOS family. It features four independent comparators with open-drain outputs in a 14-TSSOP package. The device operates on a single supply voltage ranging from 3V to 16V. It offers low input bias current and rail-to-rail output capability, making it suitable for general-purpose comparison tasks in surface-mount applications.

Comparators Feature Summary

• Quad configuration with independent channels
• LinCMOS technology for micropower operation
• Open-drain output structure
• Rail-to-rail output swing

Comparators Applications

• General-purpose voltage monitoring
• Threshold detection circuits
• Simple analog signal conditioning
• Battery level indication systems

Comparators Procurement Notes

Verify the specific suffix CDBR against the official Texas Instruments datasheet to confirm package dimensions and thermal characteristics. Ensure the component source is an authorized distributor to avoid counterfeit parts. Check for RoHS compliance status as per the latest manufacturer documentation.

Comparators Selection Notes

Select this part when a quad comparator with low power consumption is required. Consider the open-drain output limitation which requires external pull-up resistors. Evaluate the operating temperature range and supply voltage compatibility with the target system design before finalizing the component choice.

Comparators Part Context

This component is part of the broader TLC339 series of comparators. It shares functional similarities with other members like the TLC339CPWR but differs in packaging. The LinCMOS process allows for operation at lower voltages compared to bipolar counterparts while maintaining reasonable speed.

Comparators Replacement Considerations

Official parameter-equivalent substitutes include the TLC339CD. Verify pinout compatibility and electrical specifications before substitution. Alternative packages such as TSSOP or SOIC variants may require board layout adjustments.
