TLV3704ID

Comparators Overview

The TLV3704ID is a quad nanopower voltage comparator from Texas Instruments, housed in a 14-pin SOIC package. It operates on a single supply ranging from 2.5V to 16V or split supplies up to ±8V. The device draws only 560nA per channel at 25°C and features an input common-mode range extending from -0.1V to VCC + 5V. It includes reverse battery protection up to 20V and push-pull CMOS outputs. The industrial grade variant supports temperatures from -40°C to 125°C.

Comparators Feature Summary

• Nanopower consumption with 560nA per channel supply current
• Input common-mode range exceeds rails by 5V above positive supply
• Reverse battery protection up to 20V for harsh environments
• Push-pull CMOS output stage eliminates need for external pull-up resistors

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 'I' indicates the industrial temperature range of -40°C to 125°C. Confirm the 'D' suffix corresponds to the SOIC-14 package type. Ensure design compatibility with the specified 2.5V to 16V operating voltage range and check for any documentation updates regarding availability.

Comparators Selection Notes

Select this component when ultra-low quiescent current is critical for battery life. The over-the-rail input capability allows signal comparison even when inputs exceed the positive supply rail. The push-pull output simplifies interface logic without requiring additional pull-up components, reducing board space and power loss.

Comparators Part Context

This part belongs to the TLV370x family of nanopower comparators, designed specifically for applications where power conservation is paramount. Unlike micropower alternatives, the TLV370x offers significantly lower supply current while maintaining robust input protection features suitable for direct battery connection.

Comparators Replacement Considerations

The TLC3704 series serves as a higher-speed alternative but consumes significantly more current. The TLV3704CD is the commercial grade equivalent with a restricted temperature range of 0°C to 70°C. Verify thermal requirements before substituting between industrial and commercial grades.

Comparators FAQ

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

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.

Does the TLV3704 require an external pull-up resistor?

No, the device features a push-pull CMOS output stage that drives both high and low states, eliminating the need for external pull-up resistors.

How does the Power-On Reset (POR) circuit affect startup?

The internal POR circuit holds the output low for approximately 3ms after the supply voltage crosses 1.5V, ensuring a known start-up condition.
