TLC3702QDRG4Q1

Comparators Overview

The TLC3702QDRG4Q1 is a dual-channel automotive-grade analog comparator from Texas Instruments, housed in an 8-SOIC package. It features rail-to-rail input capability and push-pull outputs. The device operates within a supply voltage range of 4V to 16V. Key electrical specifications include a maximum propagation delay of 4.5µs, a typical CMRR and PSRR of 84dB, and a maximum input offset voltage of 5mV at 10V. It supports a wide operating temperature range from -40°C to 125°C and holds AEC-Q100 qualification.

Comparators Feature Summary

• Automotive-grade reliability with AEC-Q100 certification for robust performance in vehicle environments.
• Rail-to-rail input stage allows signal detection across the full common-mode voltage range.
• Push-pull output architecture provides strong drive capability compatible with CMOS, TTL, and logic families.

Comparators Applications

• Automotive sensor interface circuits
• Voltage monitoring systems
• Threshold detection applications

Comparators Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm that the specific suffix matches the required automotive grade and packaging format. Ensure compliance with RoHS directives and check for any relevant PCN or EOL notices prior to final design integration.

Comparators Selection Notes

Select this component when automotive qualification is mandatory and rail-to-rail input coverage is required. Compare against standard industrial variants if automotive certification is unnecessary. Consider the 4.5µs propagation delay for timing-sensitive designs requiring moderate speed.

Comparators Part Context

This part belongs to the TLC3702 family of dual comparators. It shares functional similarities with other members like the TLC3702IDR but differs in automotive qualification status. The QDRG4Q1 designation indicates specific manufacturing and quality controls tailored for automotive supply chains.

Comparators Replacement Considerations

TLC3702MDR is listed as a parameter-equivalent alternative. Verify pinout compatibility and electrical limits before substitution. Other family members may require re-evaluation of automotive requirements.
