TLC374CDG4

Comparators Overview

The TLC374CDG4 is a quad precision comparator from Texas Instruments, part of the LinCMOS family. It features four independent differential comparators in a 14-SOIC package. Key electrical parameters include a maximum input offset voltage of 5mV at 5V and a maximum input bias current of 5pA at 5V. The device operates with a single supply voltage range of 3V to 16V or dual supplies of ±1.5V to ±8V. It delivers a typical output current of 20mA and has a maximum static current consumption of 800µA. The operational temperature range extends from -40°C to +85°C.

Comparators Feature Summary

• LinCMOS technology enables low power consumption while maintaining high-speed performance.
• Quad configuration integrates four independent differential comparators into a single compact package.
• Versatile output stage supports CMOS, MOS, open-drain, and TTL logic levels for broad compatibility.

Comparators Applications

• Precision voltage monitoring circuits
• Window detector applications
• Analog-to-digital converter interfaces

Comparators Procurement Notes

Verify the specific suffix G4 indicates lead-free and RoHS compliance status according to manufacturer documentation. Confirm the SOIC-14 package dimensions match PCB footprint requirements. Check for any recent Product Change Notifications (PCN) regarding design or specification updates. Ensure the operating temperature range meets system environmental constraints. Validate that the output drive capability satisfies downstream load requirements.

Comparators Selection Notes

Select this component when multiple independent comparison functions are required in a space-constrained design. The low input bias current makes it suitable for high-impedance sensor interfaces. Consider the output flexibility if interfacing with mixed-voltage logic families. Evaluate the static current consumption against total system power budgets. Compare the speed and offset specifications against alternative comparators for critical timing applications.

Comparators Part Context

This device belongs to Texas Instruments' LinCMOS product line, which combines CMOS density with bipolar-like performance. The TLC374 series offers a quad comparator solution, providing cost-effective integration compared to discrete components. It serves as a standard general-purpose comparator for industrial and consumer electronics requiring reliable signal threshold detection.

Comparators Replacement Considerations

The TLC374IDR is listed as a parameter-compatible substitute within the same manufacturer portfolio. Verify pinout and electrical specifications before substitution. Other generic quad comparators may require circuit redesign due to differing output structures or supply ranges.
