TLV3404IPW Equivalent & Substitute Parts

Part Overview

The TLV3404IPW is a general-purpose CMOS comparator with open-drain output, featuring four independent elements in a 14-TSSOP surface-mount package. This device operates across a wide supply voltage range of 2.7V to 16V (single supply) or ±1.35V to ±8V (dual supply), making it suitable for precision analog signal comparison applications.

The TLV3404IPW is classified as obsolete. Equivalent and substitute parts are necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades. Substitute parts must maintain functional compatibility while meeting the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV3404IPW is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Number of elements: 4 independent comparators
• Output type: CMOS, Open-Drain configuration
• Supply voltage range: Must support the application's operating voltage
• Input offset voltage: Maximum specification at rated voltage
• Input bias current: Maximum specification at rated voltage
• Quiescent current: Power consumption profile
• CMRR and PSRR: Signal rejection performance
• Propagation delay: Timing performance
• Operating temperature range: -40°C ~ 125°C

Mechanical Compatibility Requirements:

• Package type: 14-TSSOP or equivalent footprint
• Mounting type: Surface Mount
• Pin configuration: Functional pin compatibility

Compliance Requirements:

• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Substitute parts are grouped into two categories:

Category 1 - Direct Equivalents (Identical Specifications): TLV3404IPWR is the active production equivalent of TLV3404IPW, maintaining identical electrical specifications and 14-TSSOP packaging.

Category 2 - Functional Substitutes (Relaxed Specifications): MAX994EUD+, MAX996EUD+, MAX996EUD+T, and MCP6569T-E/SL provide comparable functionality with trade-offs in supply voltage range, input offset voltage, quiescent current, or package type. These parts are suitable for applications where the relaxed specifications remain within design margins.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: TLV3404IPWR

TLV3404IPWR is the direct active equivalent of the obsolete TLV3404IPW. This part maintains identical electrical specifications, identical 14-TSSOP packaging, and identical pin configuration. TLV3404IPWR is classified as active product status with ROHS3 compliance and MSL 1 rating. This part is the preferred choice for direct replacement in existing designs.

Secondary Recommendations: MAX994EUD+, MAX996EUD+, MAX996EUD+T

These Analog Devices/Maxim Integrated parts provide functional substitution for applications operating within the 2.5V to 5.5V supply range. All three parts maintain 14-TSSOP packaging and CMOS open-drain output configuration. These parts are active products with ROHS3 compliance and MSL 1 rating. Selection among these three depends on quiescent current and propagation delay requirements:

• MAX994EUD+ offers the lowest quiescent current (24µA) with slower propagation delay (450ns)
• MAX996EUD+ and MAX996EUD+T offer identical specifications with faster propagation delay (210ns) and higher quiescent current (96µA)

These parts are not suitable for applications requiring supply voltages above 5.5V or below 2.5V.

Tertiary Recommendation: MCP6569T-E/SL

MCP6569T-E/SL is a Microchip Technology comparator providing functional substitution with the following considerations:

• Package type is 14-SOIC rather than 14-TSSOP, requiring PCB layout modification
• Supply voltage range extends to 1.8V minimum, supporting lower-voltage applications
• Operating temperature range matches the original part (-40°C ~ 125°C)
• Propagation delay is significantly faster (80ns)
• Output current capability is higher (50mA typical)
• CMRR and PSRR performance is reduced compared to the original part

MCP6569T-E/SL is active product status with ROHS3 compliance and MSL 1 rating. This part is suitable only for applications where PCB layout modification is acceptable and where the reduced signal rejection performance remains within design margins.

Frequently Asked Questions (FAQ)

Q: Can TLV3404IPWR be used as a direct replacement for TLV3404IPW?

A: Yes. TLV3404IPWR is the active production equivalent with identical electrical specifications, package type, and pin configuration. The only difference is product status: TLV3404IPW is obsolete while TLV3404IPWR is active.

Q: What is the key limitation when using MAX994EUD+, MAX996EUD+, or MAX996EUD+T as substitutes?

A: The maximum supply voltage is limited to 5.5V (single supply) or ±2.75V (dual supply), compared to the original part's 16V (single supply) or ±8V (dual supply). These parts are suitable only for applications operating within this reduced voltage range.

Q: Why does MCP6569T-E/SL require PCB layout modification?

A: MCP6569T-E/SL uses a 14-SOIC package (0.154", 3.90mm width) instead of the 14-TSSOP package (0.173", 4.40mm width) of the original part. The different package footprint requires PCB layout changes and component placement adjustment.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (TLV3404IPWR, MAX994EUD+, MAX996EUD+, MAX996EUD+T, and MCP6569T-E/SL) are ROHS3 compliant with MSL 1 (Unlimited) rating, matching the original part's compliance profile.

Q: Which substitute part offers the fastest propagation delay?

A: MCP6569T-E/SL offers the fastest propagation delay at 80ns maximum, compared to 300µs for the original part and 210ns to 450ns for the Maxim Integrated alternatives. However, this faster performance comes with reduced CMRR and PSRR specifications.

Q: Can I use multiple substitute parts interchangeably in the same design?

A: No. Each substitute part has different electrical specifications. Once a substitute part is selected for a design, it should be used consistently. Mixing different substitute parts in the same application may result in performance variations or functional incompatibility.
