TLC3704CPWR

Comparators Overview

The TLC3704CPWR is a quad micro-power voltage comparator manufactured by Texas Instruments, utilizing LinCMOS technology. It features four independent channels with push-pull outputs capable of sourcing or sinking up to 20 mA. The device operates on a single supply voltage ranging from 3 V to 16 V, with a typical quiescent current of 50 µA. Key electrical specifications include a maximum input offset voltage of 5 mV and an input bias current of 5 pA at 5 V. The propagation delay is typically 4.5 µs, and the common-mode rejection ratio is 84 dB. It is housed in an 8-TSSOP package and supports operation within a temperature range of 0°C to +70°C.

Comparators Feature Summary

• Quad channel configuration with high-current push-pull outputs for direct interfacing with digital logic.
• Micro-power consumption design suitable for battery-operated applications.
• LinCMOS technology provides rail-to-rail input capability and CMOS-compatible output levels.

Comparators Applications

• Battery-powered monitoring systems
• Threshold detection circuits
• Simple analog-to-digital conversion interfaces

Comparators Procurement Notes

Verify the specific suffix CPWR indicates the commercial temperature grade (0°C to +70°C) and TSSOP-8 packaging. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the ordering part number matches the required pinout and thermal characteristics for the target PCB layout.

Comparators Selection Notes

Select this component when low power consumption is critical alongside the need for multiple comparator channels in a small footprint. The push-pull output eliminates the need for external pull-up resistors, simplifying circuit design compared to open-collector alternatives. Consider the 4.5 µs propagation delay for timing-sensitive applications.

Comparators Part Context

The TLC3704 belongs to the LinCMOS family of comparators, designed to offer performance comparable to bipolar devices while maintaining CMOS power efficiency. This series includes variants with different channel counts and packages, such as the dual-channel TLC3702 and industrial/automotive graded versions like the TLC3704ID or TLC3704QDRG4Q1.

Comparators Replacement Considerations

Direct pin-compatible replacements include other quad comparators from the same family, such as the TLC3704CD or TLC3704ID, depending on the required temperature range. Cross-brand equivalents may require verification of pinout compatibility and electrical parameter alignment.
