TLC3702MDR

Comparators Overview

The TLC3702MDR is a dual micropower voltage comparator utilizing Texas Instruments' LinCMOS process, housed in an SOIC-8 surface-mount package. It operates on a single supply ranging from 4 V to 16 V and features push-pull CMOS outputs capable of driving capacitive loads directly without pullup resistors. The device provides a typical propagation delay of 2.7 μs with 5-mV overdrive and maintains low power consumption at approximately 100 μW typ at 5 V. Designed for the full military temperature range of -55°C to 125°C, it includes on-chip ESD protection and offers high input impedance with extremely stable input offset voltages.

Comparators Feature Summary

• Push-pull CMOS output stage drives capacitive loads directly without requiring external pullup resistors
• LinCMOS process ensures superior analog performance with extremely stable input offset voltages under large differential input conditions
• Integrated on-chip electrostatic discharge (ESD) protection circuitry safeguards against gate oxide breakdown

Comparators Applications

• Single-supply signal conditioning circuits compatible with HCMOS logic systems
• Low-power threshold detection applications requiring minimal board space
• Military-grade electronic systems operating within extended temperature ranges

Comparators Procurement Notes

Verify that the specific part number suffix 'M' corresponds to the full military temperature rating (-55°C to 125°C) rather than commercial or industrial grades. Confirm the 'DR' suffix indicates the tape-and-reel packaging format for the SOIC-8 variant. Ensure compatibility with single-supply operation requirements between 4 V and 16 V before integration into the design.

Comparators Selection Notes

Select this component when designing for environments requiring operation down to -55°C, as other variants like the TLC3702C are limited to 0°C. Consider the push-pull output capability if eliminating external pullup resistors is necessary to reduce power dissipation and component count. Evaluate the 2.7 μs propagation delay against system timing constraints compared to faster general-purpose comparators.

Comparators Part Context

This device belongs to the TLC3702 family of dual micropower comparators. While functionally similar to the LM339, it utilizes one-twentieth of the power for comparable response times. The family includes variants such as the TLC3702CD for commercial use and TLC3702ID for industrial applications, distinguished primarily by their specified operating temperature ranges and packaging options.
