TLV3704IDG4

Comparators Overview

The TLV3704IDG4 is a quad nanopower comparator from Texas Instruments featuring push-pull CMOS outputs. It operates on a single supply voltage ranging from 2.5V to 16V, with an extended industrial temperature range of -40°C to +125°C. The device draws only 560nA per channel at 2.7V and supports an input common-mode range extending from -0.1V to VCC + 5V. Packaged in a 14-pin SOIC, it includes reverse battery protection up to 20V and internal power-on reset circuitry for reliable startup.

Comparators Feature Summary

• Nanopower consumption with 560nA per channel supply current
• Over-the-rail input common-mode range extending to VCC + 5V
• Reverse battery protection up to 20V
• Internal power-on reset circuitry

Comparators Applications

• Portable battery monitoring systems
• Consumer medical electronics
• Security detection systems
• Handheld instruments
• Ultra-low power wireless applications

Comparators Procurement Notes

Verify the specific suffix 'DGK' indicates the MSOP package variant rather than the standard SOIC package associated with the base model number. Confirm the industrial grade temperature rating aligns with system requirements. Check for end-of-life status or obsolescence notices before finalizing design-in decisions.

Comparators Selection Notes

Select this component when ultra-low quiescent current is critical compared to standard micropower comparers. The over-the-rail input capability allows operation at low supply voltages without limiting input signal range. Ensure the 14-pin SOIC footprint matches the PCB layout constraints.

Comparators Part Context

This part belongs to the TLV370x family of nanopower comparators, which are designed specifically for battery-powered and wireless handset applications where minimizing supply current is the primary design constraint. The family includes single, dual, and quad variants sharing similar electrical characteristics.

Comparators Replacement Considerations

Official substitutes within the same family include the TLV3701 and TLV3702, though pin counts differ. For quad configurations, verify if other TI comparers like the TLC3704 meet the specific nanopower requirements, noting differences in supply current and input stage architecture.

Comparators FAQ

What is the maximum input voltage allowed relative to the supply rail?

The input common-mode range extends from -0.1V to VCC + 5V, allowing inputs to exceed the positive supply rail by up to 5V without damage.

How does the Power-On Reset (POR) function operate?

The internal POR circuit holds the output low for up to 3ms after the supply voltage crosses 1.5V, ensuring known start-up conditions before the comparator reflects differential input states.
