TLC372QDRG4

Comparators Overview

The TLC372QDRG4 is a dual-channel analog comparator from Texas Instruments, part of the LinCMOS family. It operates on a single supply voltage ranging from 4V to 16V or dual supplies of ±2V to ±8V. The device features push-pull outputs capable of sourcing and sinking up to 20mA. Key electrical specifications include a maximum input offset voltage of 5mV at 5V, an input bias current of 5pA at 5V, and a typical common-mode rejection ratio of 84dB. It functions within a temperature range of -40°C to +125°C and is housed in an 8-SOIC package.

Comparators Feature Summary

• LinCMOS technology enables low power consumption while maintaining high-speed performance.
• Push-pull output stage provides direct interfacing with TTL, CMOS, and MOS logic families without requiring external pull-up resistors.
• Differential inputs support standard single-supply operation for simplified circuit design.

Comparators Applications

• General-purpose signal comparison in industrial control systems
• Threshold detection circuits for battery management
• Interface between analog sensors and digital logic controllers

Comparators Procurement Notes

Verify the complete ordering code includes the G4 suffix to confirm lead-free and RoHS compliance status. Ensure the SOIC-8 package variant matches the PCB footprint requirements. Confirm the Q1 or standard grade designation aligns with the specific automotive or commercial reliability needs of the target application environment.

Comparators Selection Notes

Select this component when a dual-channel solution is required with push-pull outputs to eliminate external components. Compare against single-channel alternatives if space is constrained, noting that the quad version offers higher integration. Evaluate the 5mV offset voltage specification against the precision requirements of the sensing application to ensure adequate accuracy margins.

Comparators Part Context

This device belongs to the TLC37x series of micro-power comparators. It shares architectural similarities with the TLC3702 but differs in channel count and specific pinout configurations. The series utilizes LinCMOS technology to balance low quiescent current with fast propagation delays suitable for general-purpose applications.

Comparators Replacement Considerations

The TLC372DR serves as a non-automotive grade equivalent. For automotive applications, verify compatibility with the TLC372QDR variant. Cross-reference pinouts carefully when substituting with other dual comparators to ensure correct supply and output alignment.
