TLV3404IDG4 Equivalent & Substitute Parts

Part Overview

The TLV3404IDG4 is a general-purpose CMOS comparator with open-drain output configuration, designed for applications requiring low-power signal comparison across a wide supply voltage range. Manufactured by Texas Instruments, this 4-element comparator IC is housed in a 14-SOIC surface-mount package.

The TLV3404IDG4 carries an obsolete product status, making it necessary to identify functionally equivalent alternatives for new designs or ongoing production requirements. Substitute parts must maintain electrical compatibility across key parameters including supply voltage range, input offset voltage, bias current characteristics, and output configuration to ensure direct replacement capability.

Substitute Categories:

Category 1: Direct Texas Instruments Equivalents TLV3404IDR and TLV3404ID are die-identical variants of the TLV3404IDG4, differing only in packaging format (Tape & Reel versus tube). These parts maintain identical electrical specifications and are fully interchangeable at the functional level.

Category 2: Maxim Integrated Alternatives (MAX994 and MAX996 Series) The MAX994ESD+, MAX994ESD+T, MAX996ESD+, and MAX996ESD+T represent functional alternatives with different electrical characteristics. These parts operate within a narrower supply voltage range (2.5V ~ 5.5V) and exhibit different propagation delay and quiescent current specifications. Substitution requires verification that the application's supply voltage and performance requirements align with these alternative specifications.

Engineering Selection Recommendations

For Direct Replacement (Preferred): TLV3404IDR is the recommended substitute for the obsolete TLV3404IDG4. This part maintains identical electrical specifications and operating characteristics while carrying an active product status. The only difference is packaging format (Tape & Reel versus tube), which does not affect functional performance. TLV3404IDR is available in higher inventory quantities (13,238 units) compared to the original part.

For Extended Supply Voltage Applications: If the application requires operation beyond the 2.5V ~ 5.5V range supported by Maxim alternatives, the TLV3404IDR remains the only viable option among the listed substitutes.

For Lower Quiescent Current Requirements: The MAX994ESD+ and MAX994ESD+T series offer significantly lower quiescent current (24µA maximum) compared to the TLV3404IDG4 (950nA maximum). However, substitution requires verification that the application's supply voltage operates within the 2.5V ~ 5.5V range and that the reduced operating temperature range (-40°C ~ 85°C) is acceptable.

For Faster Propagation Delay: The MAX996ESD+ and MAX996ESD+T series provide faster propagation delay (210ns maximum) compared to the TLV3404IDG4 (300µs maximum). These parts are suitable only for applications where supply voltage remains within 2.5V ~ 5.5V and operating temperature does not exceed 85°C.

All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can TLV3404IDR be used as a direct replacement for TLV3404IDG4? A: Yes. TLV3404IDR is electrically identical to TLV3404IDG4 and differs only in packaging format (Tape & Reel versus tube). Both parts maintain the same electrical specifications, operating temperature range, and performance characteristics. TLV3404IDR carries an active product status and is available in higher quantities.

Q: What are the key differences between TLV3404 series and MAX994/MAX996 series? A: The primary differences are supply voltage range, quiescent current, and propagation delay. TLV3404 operates from 2.7V ~ 16V with 950nA quiescent current and 300µs propagation delay. MAX994 operates from 2.5V ~ 5.5V with 24µA quiescent current and 450ns propagation delay. MAX996 operates from 2.5V ~ 5.5V with 96µA quiescent current and 210ns propagation delay. Substitution requires verification that the application's supply voltage and performance requirements align with these specifications.

Q: Can MAX994ESD+ or MAX996ESD+ be used in applications requiring supply voltages above 5.5V? A: No. The maximum supply voltage for MAX994 and MAX996 series is 5.5V. Applications requiring operation at higher supply voltages must use TLV3404IDR or TLV3404ID.

Q: What is the difference between MAX994ESD+ and MAX994ESD+T? A: Both parts are electrically identical. The difference is packaging format: MAX994ESD+ is supplied in tube packaging, while MAX994ESD+T is supplied in Tape & Reel format. Selection depends on production requirements and handling preferences.

Q: Are all substitute parts available in the same 14-SOIC package? A: Yes. All listed substitute parts are housed in 14-SOIC (0.154", 3.90mm Width) surface-mount packages, ensuring mechanical compatibility with existing PCB layouts.

Q: Do all substitute parts meet the same compliance standards as TLV3404IDG4? A: Yes. All substitute parts listed are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the original part.

Q: What is the operating temperature range difference between TLV3404 and MAX994/MAX996 series? A: TLV3404 operates from -40°C ~ 125°C, while MAX994 and MAX996 series operate from -40°C ~ 85°C. Applications requiring operation above 85°C must use TLV3404IDR or TLV3404ID.
