TLV3404CPW Equivalent & Substitute Parts

Part Overview

The TLV3404CPW is a general-purpose CMOS comparator with open-drain output configuration, housed in a 14-TSSOP surface-mount package. This device is classified as obsolete, which necessitates identification of active equivalent parts for ongoing design support and procurement. The TLV3404CPW operates across a wide supply voltage range (2.5V to 16V single supply, ±1.25V to ±8V dual supply) and is suitable for precision analog signal comparison applications requiring low quiescent current and high common-mode rejection.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV3404CPW is determined by the following critical parameters:

Mechanical Compatibility: All substitute parts must use the 14-TSSOP package with identical 0.173" (4.40mm) width to ensure PCB footprint compatibility.

Functional Equivalence: Substitute parts must provide four independent comparator elements with CMOS open-drain output configuration.

Electrical Operating Range: The supply voltage range defines the primary substitution constraint. The TLV3404CPW operates from 2.5V to 16V (single supply) or ±1.25V to ±8V (dual supply). Substitute parts must support the voltage range required by the application.

Performance Characteristics: Input offset voltage, input bias current, quiescent current, and propagation delay are secondary selection criteria. Parts with equivalent or superior performance characteristics within the same voltage class are acceptable substitutes.

Compliance & Status: Active product status and ROHS3 compliance are required for new designs and procurement continuity.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TLV3404IPWR

The TLV3404IPWR is the direct active equivalent from Texas Instruments. It maintains identical electrical performance specifications (3.6mV input offset, 250pA input bias current, 950nA quiescent current, 300µs propagation delay) and supports the same extended supply voltage range (2.7V to 16V single supply, ±1.35V to ±8V dual supply). The TLV3404IPWR is active product status with ROHS3 compliance and extended operating temperature range (-40°C to 125°C), providing superior long-term availability and design support.

Alternative Substitutes: MAX994EUD+, MAX996EUD+, MAX996EUD+T

The Maxim Integrated comparators (MAX994EUD+, MAX996EUD+, MAX996EUD+T) are functionally compatible alternatives with identical 14-TSSOP packaging and four-element configuration. These parts are suitable only for applications operating within the 2.5V to 5.5V supply voltage range. The MAX996 variants offer faster propagation delay (210ns) compared to the TLV3404CPW (300µs), while the MAX994 provides intermediate performance (450ns). All three Maxim parts are active product status with ROHS3 compliance.

Voltage Range Constraint: Applications requiring supply voltages above 5.5V must use TLV3404IPWR. Applications limited to 5.5V or below may select from all available substitutes based on performance and temperature requirements.

Frequently Asked Questions (FAQ)

Q: Can the MAX994EUD+ or MAX996EUD+ replace the TLV3404CPW in all applications?

A: No. The Maxim parts operate only within 2.5V to 5.5V supply range, while the TLV3404CPW supports up to 16V. Substitution is valid only for applications operating within the 2.5V to 5.5V range. For higher voltage applications, use TLV3404IPWR.

Q: What is the difference between MAX996EUD+ and MAX996EUD+T?

A: Both parts are electrically identical with 210ns propagation delay and 96µA quiescent current. The difference is packaging format: MAX996EUD+ is supplied in Tube, while MAX996EUD+T uses an alternative packaging configuration. Both are mechanically compatible with the 14-TSSOP footprint.

Q: Is TLV3404IPWR a direct drop-in replacement for TLV3404CPW?

A: Yes. The TLV3404IPWR uses the identical 14-TSSOP package, provides the same electrical performance, and supports the same supply voltage range. It is the recommended substitute for obsolete TLV3404CPW designs.

Q: Why do the Maxim parts show faster propagation delay than the TLV3404CPW?

A: The MAX996 series (210ns) and MAX994 series (450ns) are optimized for lower voltage operation (2.5V to 5.5V). The TLV3404CPW is designed for extended voltage range (up to 16V), which results in different propagation delay characteristics. Faster propagation delay in lower voltage parts does not indicate superior performance for all applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. TLV3404IPWR, MAX994EUD+, MAX996EUD+, and MAX996EUD+T are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the operating temperature range difference between TLV3404CPW and TLV3404IPWR?

A: The obsolete TLV3404CPW operates 0°C to 70°C. The active TLV3404IPWR extends this to -40°C to 125°C, providing broader environmental coverage for industrial and automotive applications.
