TLV3402IDR

Comparators Overview

The TLV3402IDR is a dual-channel analog comparator manufactured by Texas Instruments, housed in an 8-SOIC surface-mount package. It operates on a single or dual supply voltage ranging from 2.7V to 16V (±1.35V to ±8V). Key electrical specifications include a maximum propagation delay of 300µs, typical CMRR and PSRR values of 88dB and 105dB respectively, and a maximum input offset voltage of 3.6mV at 15V. The device features CMOS open-drain outputs capable of sourcing up to 10mA, with a maximum quiescent current of 950nA and input bias current of 250pA at 15V. It supports an operating temperature range of -40°C to 125°C.

Comparators Feature Summary

• Dual-channel configuration providing two independent comparison functions within a single compact package.
• CMOS open-drain output stage allows for flexible interfacing with various logic families and voltage levels.
• Low static power consumption suitable for battery-operated applications requiring extended operational life.

Comparators Applications

• General-purpose signal conditioning circuits
• Threshold detection systems
• Simple analog-to-digital conversion interfaces

Comparators Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status as regulatory requirements may vary by production batch. Cross-reference the component marking code with official identification guides to prevent counterfeit substitution during assembly.

Comparators Selection Notes

Select this component when a low-cost, dual-channel solution is required for basic threshold monitoring. Ensure the application voltage does not exceed the 16V absolute maximum rating. Consider the 300µs propagation delay if high-speed switching is necessary, as faster alternatives exist within the family.

Comparators Part Context

This part belongs to the TLV340x series of comparators, which includes quad (TLV3404) and single (TLV3401) channel variants. The ID suffix indicates the industrial temperature grade and SOIC package type. It serves as a general-purpose alternative to higher-speed specialized comparators where cost and pin count are primary constraints.

Comparators Replacement Considerations

Direct pin-compatible substitutes include the TLV3401IDR (single channel) and TLV3404IDR (quad channel) from the same series. Verify that the replacement meets the specific voltage and temperature requirements of the design.
