TLV3704ID Equivalent & Substitute Parts

Part Overview

The TLV3704ID is a general-purpose CMOS comparator manufactured by Texas Instruments, featuring four independent comparator elements in a 14-SOIC package. This device operates across a wide supply voltage range (2.7V to 16V single supply, or ±1.35V to ±8V dual supply) with rail-to-rail output capability and push-pull configuration. The TLV3704ID is currently in Last Time Buy status, indicating end-of-life production. Identifying equivalent and substitute parts is necessary to ensure design continuity and maintain component availability for ongoing production and maintenance requirements.

Substitute Part Grouping Explanation

Substitute parts for the TLV3704ID are grouped based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Number of comparator elements: 4 (mandatory match)
• Output type: CMOS, Push-Pull, Rail-to-Rail (mandatory match)
• Supply voltage range compatibility: Must support the application's operating voltage
• Package compatibility: Surface mount, SOIC or TSSOP variants acceptable
• Operating temperature range: Must cover -40°C to 125°C or application-specific requirements
• Compliance: ROHS3 compliant, MSL 1

Substitution Groups:

Group 1 - Direct Package Equivalent (14-SOIC): TLV3704IPWR, MAX993ESD+, MAX993ESD+T, MAX995ESD+, MAX995ESD+T maintain identical 14-SOIC packaging with full electrical compatibility within their respective supply voltage ranges.

Group 2 - Alternative Package (14-TSSOP): TLV3704IPWR (14-TSSOP variant) provides Texas Instruments continuity with different package geometry but identical electrical specifications.

Group 3 - Extended Feature Set (16-QSOP): MAX978EEE+T offers four comparators in 16-QSOP packaging with enhanced specifications including lower propagation delay (28ns) and integrated hysteresis (4mV), though with restricted supply voltage range (2.7V to 5.5V).

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Supply Voltage Range): TLV3704IPWR is the primary recommended substitute, offering identical electrical specifications and operating temperature range (-40°C to 125°C) as the TLV3704ID. Both devices are Texas Instruments products with ROHS3 compliance and MSL 1 rating. The only difference is packaging: TLV3704IPWR is available in 14-TSSOP format with Cut Tape & Digi-Reel packaging, while TLV3704ID uses 14-SOIC in Tube packaging. This substitution requires PCB layout modification to accommodate the different package footprint.

For Applications Limited to 2.5V to 5.5V Supply Range: MAX993ESD+, MAX993ESD+T, MAX995ESD+, and MAX995ESD+T are suitable substitutes when the application operates exclusively within 2.5V to 5.5V supply voltage. These Analog Devices/Maxim devices maintain 14-SOIC packaging compatibility with the TLV3704ID. All four variants are ROHS3 compliant with MSL 1 rating and active product status. Selection between MAX993 and MAX995 variants depends on quiescent current requirements (MAX993: 24µA vs. MAX995: 96µA) and propagation delay specifications (MAX993: 450ns vs. MAX995: 210ns). Packaging variants differ only in delivery format (Tube vs. Tape & Reel).

For Extended Operating Temperature or Enhanced Performance: MAX978EEE+T provides four comparators in 16-QSOP packaging with superior input offset voltage (2mV @ 5V) and integrated hysteresis (4mV). However, this device is restricted to 2.7V to 5.5V supply range and -40°C to 85°C operating temperature, making it unsuitable for applications requiring the TLV3704ID's extended temperature range or higher supply voltages.

Compliance and Regulatory Considerations: All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage requirements. All devices are classified as EAR99 with identical HTSUS codes, maintaining consistent regulatory treatment.

Frequently Asked Questions (FAQ)

Q: Can I use MAX993ESD+ or MAX995ESD+ as a direct replacement for TLV3704ID without PCB modifications?

A: MAX993ESD+ and MAX995ESD+ maintain identical 14-SOIC packaging as TLV3704ID, allowing direct PCB footprint compatibility. However, these devices operate only within 2.5V to 5.5V supply range, compared to TLV3704ID's 2.7V to 16V range. Substitution is valid only if your application operates within the restricted voltage range. Additionally, operating temperature is limited to -40°C to 85°C versus TLV3704ID's -40°C to 125°C.

Q: What is the difference between MAX993ESD+ and MAX995ESD+?

A: Both devices are 4-element comparators in 14-SOIC packaging with identical supply voltage range (2.5V to 5.5V) and operating temperature (-40°C to 85°C). The primary differences are quiescent current (MAX993: 24µA maximum vs. MAX995: 96µA maximum) and propagation delay (MAX993: 450ns maximum vs. MAX995: 210ns maximum). Select MAX993 for low-power applications and MAX995 for faster response requirements.

Q: Why does TLV3704IPWR use 14-TSSOP packaging instead of 14-SOIC?

A: TLV3704IPWR is the active production variant of the TLV3704 series, offered in 14-TSSOP (Thin Shrink Small Outline Package) format. This package provides smaller footprint dimensions (0.173" width vs. 0.154" for SOIC) while maintaining identical electrical performance. PCB layout redesign is required to accommodate the different pin configuration and package geometry.

Q: Is MAX978EEE+T compatible with applications requiring supply voltages above 5.5V?

A: No. MAX978EEE+T operates only within 2.7V to 5.5V supply range. Applications requiring higher supply voltages (up to 16V as supported by TLV3704ID) cannot use this device. Additionally, MAX978EEE+T is limited to -40°C to 85°C operating temperature, restricting use in applications requiring extended temperature range to 125°C.

Q: What packaging options are available for substitute parts?

A: TLV3704IPWR is available in 14-TSSOP with Cut Tape & Digi-Reel packaging. MAX993ESD+ and MAX995ESD+ are available in Tube packaging (14-SOIC). MAX993ESD+T and MAX995ESD+T are available in Tape & Reel format (14-SOIC). MAX978EEE+T is supplied in Tape & Reel format (16-QSOP). Select packaging based on production volume and handling requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (TLV3704IPWR, MAX993ESD+, MAX993ESD+T, MAX995ESD+, MAX995ESD+T, and MAX978EEE+T) are ROHS3 compliant with MSL 1 rating, ensuring compatibility with standard manufacturing processes and environmental regulations.

Q: What is the inventory status of substitute parts?

A: TLV3704IPWR has 3,300 pieces in stock. MAX978EEE+T has 2,800 pieces. MAX993ESD+ has 2,030 pieces. MAX993ESD+T has 2,996 pieces. MAX995ESD+ has 2,100 pieces. MAX995ESD+T has 3,900 pieces. All substitute parts are in active production status with new original inventory available.
