TLV3404IN Equivalent & Substitute Parts

Part Overview

The TLV3404IN is a general-purpose CMOS comparator with open-drain output configuration, manufactured by Texas Instruments in a 14-DIP through-hole package. This device is classified as Last Time Buy, indicating discontinued production with limited remaining inventory. Identifying equivalent and substitute parts is necessary to ensure design continuity, support long-term production requirements, and maintain supply chain flexibility for applications requiring general-purpose comparison functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV3404IN is determined by the following critical parameters:

Functional Equivalence Criteria:

• Four independent general-purpose comparator elements
• CMOS open-drain output configuration
• Operating temperature range: -40°C ~ 125°C
• Supply voltage compatibility within specified ranges

Substitution Categories:

Category 1: Same Manufacturer, Different Package (Texas Instruments) The TLV3404IPWR maintains identical electrical specifications and functional performance as the TLV3404IN. The substitution is valid based on matching base product number (TLV3404), identical electrical parameters, and equivalent CMOS open-drain output. The difference is packaging format: 14-TSSOP surface-mount versus 14-DIP through-hole. This substitution requires PCB redesign for mounting compatibility.

Category 2: Alternative Manufacturer, Different Electrical Specifications (Microchip Technology) The MCP6569-E/SL and MCP6569-E/ST are functionally equivalent comparators with four elements and CMOS open-drain output. However, these parts operate within a reduced supply voltage range (1.8V ~ 5.5V versus 2.7V ~ 16V), feature different electrical characteristics (10mV input offset versus 3.6mV, 1pA input bias versus 250pA), and exhibit significantly faster propagation delay (80ns versus 300µs). These substitutes are valid only for applications operating within the 1.8V ~ 5.5V supply range and tolerating the specified electrical parameter differences.

Parameter Comparison

Engineering Selection Recommendations

For Direct Functional Replacement (Recommended Primary Substitute): The TLV3404IPWR is the preferred substitute when supply continuity is required. This part maintains identical electrical specifications, identical base product number, and active product status. Selection of TLV3404IPWR requires PCB redesign to accommodate 14-TSSOP surface-mount packaging in place of 14-DIP through-hole mounting. This substitution introduces no electrical performance changes.

For Supply-Constrained Applications: The MCP6569-E/SL and MCP6569-E/ST are valid substitutes only for applications meeting all of the following conditions: (1) supply voltage operates within 1.8V ~ 5.5V range, (2) application tolerates reduced CMRR and PSRR performance (66dB and 70dB respectively versus 88dB and 105dB), (3) application tolerates increased input offset voltage (10mV versus 3.6mV), (4) application tolerates increased quiescent current (130µA versus 950nA), and (5) application benefits from or tolerates significantly faster propagation delay (80ns versus 300µs). MCP6569-E/SL uses 14-SOIC surface-mount packaging; MCP6569-E/ST uses 14-TSSOP surface-mount packaging.

All substitute parts maintain ROHS3 compliance and -40°C ~ 125°C operating temperature range, ensuring regulatory and thermal compatibility with the original TLV3404IN specification.

Frequently Asked Questions (FAQ)

Q: Can TLV3404IPWR be used as a direct replacement for TLV3404IN? A: TLV3404IPWR provides electrical equivalence with identical specifications. The primary difference is packaging: TLV3404IPWR uses 14-TSSOP surface-mount format versus TLV3404IN's 14-DIP through-hole format. Direct socket substitution is not possible; PCB redesign is required.

Q: What are the key differences between TLV3404IN and MCP6569 series comparators? A: The MCP6569 series operates within a narrower supply voltage range (1.8V ~ 5.5V versus 2.7V ~ 16V), exhibits higher input offset voltage (10mV versus 3.6mV), higher quiescent current (130µA versus 950nA), lower CMRR and PSRR performance, and significantly faster propagation delay (80ns versus 300µs). These differences make MCP6569 suitable only for low-voltage applications that do not require the extended supply range or precision characteristics of TLV3404.

Q: Which substitute part should be selected for a new design? A: For new designs requiring general-purpose CMOS comparator functionality with four elements and open-drain output, TLV3404IPWR is the recommended selection due to active product status and identical electrical specifications. MCP6569-E/ST offers equivalent functionality in 14-TSSOP packaging as an alternative. Selection between these parts depends on supply voltage requirements and packaging constraints.

Q: Are all substitute parts RoHS compliant? A: All listed parts, including TLV3404IN, TLV3404IPWR, MCP6569-E/SL, and MCP6569-E/ST, maintain ROHS3 compliance status.

Q: What is the impact of propagation delay differences on circuit performance? A: TLV3404IN and TLV3404IPWR specify 300µs maximum propagation delay. MCP6569 series comparators specify 80ns maximum propagation delay. Applications requiring fast comparison response benefit from MCP6569 selection. Applications designed for slower comparison response (such as threshold detection in low-frequency circuits) are unaffected by this difference.

Q: Can MCP6569 parts be used in applications designed for TLV3404IN? A: MCP6569 substitution is valid only when the application operates within 1.8V ~ 5.5V supply range and tolerates the specified electrical parameter differences. Applications requiring supply voltages above 5.5V or requiring the precision characteristics of TLV3404IN (lower input offset, lower quiescent current, higher CMRR/PSRR) must use TLV3404IPWR or TLV3404IN.
