TLV3404CPWR

Comparators Overview

The TLV3404CPWR is a quad general-purpose analog comparator manufactured by Texas Instruments. It features four independent channels housed in a 14-TSSOP surface-mount package. The device operates with a single supply voltage ranging from 2.5 V to 16 V or dual supplies of ±1.25 V to ±8 V. Key electrical specifications include a maximum propagation delay of 300 µs, a typical quiescent current of 950 nA per channel, and an input offset voltage of 3.6 mV at 15 V. The output stage utilizes a CMOS open-drain configuration capable of sourcing up to 10 mA. It supports rail-to-rail input operation and functions within a temperature range of 0°C to +70°C.

Comparators Feature Summary

• Quad-channel architecture providing four independent comparison functions in a compact footprint
• Ultra-low power consumption suitable for battery-operated applications
• CMOS open-drain output stage allowing flexible logic level interfacing
• Rail-to-rail input capability ensuring compatibility with ground-referenced signals

Comparators Applications

• Battery-powered monitoring systems requiring low standby current
• Threshold detection circuits for voltage supervision
• General-purpose signal conditioning and waveform generation
• Over-voltage and under-voltage protection schemes

Comparators Procurement Notes

Verify the specific suffix CPWR indicates the commercial temperature grade (0°C to +70°C) and tape-and-reel packaging format. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the open-drain output requirement, which necessitates external pull-up resistors for proper high-state logic levels. Cross-reference the ordering part number against the latest datasheet revision to confirm pinout and electrical parameter consistency.

Comparators Selection Notes

Select this component when multiple independent comparators are needed with minimal power draw. The open-drain output requires careful consideration of pull-up resistor values to meet speed and voltage requirements. Compare the 300 µs propagation delay against application timing constraints; faster alternatives exist if response time is critical. Verify that the 3.6 mV input offset voltage meets the precision needs of the sensing circuit. Ensure the operating voltage range aligns with the available system power rails.

Comparators Part Context

This device belongs to the TLV340x family of nanopower comparators designed for low-cost, low-power applications. The TLV3404 variant specifically integrates four channels, offering a space-efficient solution compared to using discrete single-channel units. It complements other Texas Instruments linear ICs by providing simple threshold detection without the complexity of operational amplifiers. The TSSOP-14 package facilitates automated assembly in consumer and industrial electronics manufacturing.

Comparators Replacement Considerations

Publicly confirmed substitute part numbers include TLV3404IPW for extended industrial temperature ranges and TLV3404CPWG4 for lead-free compliance variations. Direct replacements must maintain the quad-channel configuration, open-drain output type, and compatible supply voltage ranges. Verify package pinout compatibility before substitution to ensure board-level interchangeability.
