TLV3704IDR Equivalent & Substitute Parts

Part Overview

The TLV3704IDR is a general-purpose CMOS comparator IC manufactured by Texas Instruments, featuring four independent comparator elements in a 14-SOIC surface-mount package. This device operates across a wide supply voltage range of 2.7V to 16V (single/dual ±1.35V to ±8V) and delivers rail-to-rail push-pull CMOS output. The TLV3704IDR is currently in Last Time Buy status, making equivalent and substitute parts necessary for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLV3704IDR is determined by the following critical parameters:

Primary Substitution Criteria:

• Four independent comparator elements
• CMOS push-pull rail-to-rail output configuration
• 14-pin surface-mount package (SOIC or TSSOP variants acceptable)
• Operating temperature range of -40°C to 125°C minimum
• Supply voltage compatibility with 2.7V to 16V range
• ROHS3 compliance and MSL Level 1 rating

Substitute Categories:

1. Direct Package Equivalent (14-SOIC): Parts maintaining identical 14-SOIC packaging with matching electrical specifications
2. Alternative Package Form Factor (14-TSSOP): Texas Instruments TLV3704IPWR offering equivalent functionality in a thermally superior TSSOP package
3. Cross-Manufacturer Alternatives (14-SOIC): Analog Devices MAX series comparators with four elements and CMOS push-pull output in 14-SOIC packaging

Substitutes with reduced supply voltage ranges (2.5V to 5.5V) or narrower operating temperature ranges (-40°C to 85°C) represent functional alternatives for applications not requiring the full specification envelope of the TLV3704IDR.

Parameter Comparison

Engineering Selection Recommendations

Tier 1 - Recommended Direct Replacement:

TLV3704IPWR is the primary substitute for the TLV3704IDR. Both devices are manufactured by Texas Instruments, share identical electrical specifications, and maintain full compatibility with the original design. The TLV3704IPWR is in Active product status with unlimited production availability. The only difference is the package form factor: 14-TSSOP versus 14-SOIC. This substitution requires PCB layout modification to accommodate the different pin pitch and body dimensions but delivers superior thermal performance due to the TSSOP package design.

Tier 2 - Cross-Manufacturer Alternatives (Supply Voltage Restricted):

MAX993ESD+, MAX993ESD+T, MAX995ESD+, and MAX995ESD+T are functionally equivalent four-element comparators from Analog Devices Inc./Maxim Integrated. All maintain 14-SOIC packaging, identical to the TLV3704IDR, enabling direct PCB compatibility without layout changes. These devices are in Active product status with established supply chains.

Critical limitation: These MAX series comparators operate within a reduced supply voltage range of 2.5V to 5.5V (single) or ±1.25V to ±2.75V (dual), compared to the TLV3704IDR's 2.7V to 16V capability. Applications requiring supply voltages above 5.5V cannot use these substitutes. Additionally, the operating temperature range is limited to -40°C to 85°C, excluding the extended 125°C upper limit of the TLV3704IDR.

Tier 3 - Alternative Package Form Factor:

MAX978EEE+ is a four-element comparator from Analog Devices Inc./Maxim Integrated in a 16-SSOP package. This device introduces significant design constraints: the 16-pin package requires PCB redesign, and the supply voltage range is further restricted to 2.7V to 5.5V. The operating temperature range is -40°C to 85°C. This option is suitable only for applications where the 16-pin configuration is acceptable and supply voltage requirements do not exceed 5.5V.

Compliance and Certification:

All substitute parts maintain ROHS3 compliance and MSL Level 1 rating, matching the environmental and regulatory requirements of the TLV3704IDR. All devices carry EAR99 export classification and are REACH unaffected.

Frequently Asked Questions (FAQ)

Q: Can I use MAX993ESD+ or MAX995ESD+ as a direct replacement for TLV3704IDR without circuit modification?

A: Electrical substitution is possible if your application operates within the restricted supply voltage range of 2.5V to 5.5V and does not require the extended 125°C upper operating temperature. The 14-SOIC package is identical, allowing direct PCB compatibility. However, the reduced supply voltage range and narrower temperature specification must be evaluated against your design requirements.

Q: What is the primary advantage of TLV3704IPWR over TLV3704IDR?

A: TLV3704IPWR maintains identical electrical specifications and full supply voltage range (2.7V to 16V) with extended temperature operation (-40°C to 125°C). The 14-TSSOP package provides superior thermal performance compared to 14-SOIC. The trade-off is PCB layout modification to accommodate the different pin pitch (0.65mm TSSOP versus 1.27mm SOIC).

Q: Why does MAX978EEE+ have a 16-pin package when TLV3704IDR uses 14 pins?

A: MAX978EEE+ is a different device architecture with additional functional elements or pin configurations. The 16-SSOP package requires complete PCB redesign and is not recommended as a direct substitute unless the application specifically requires the additional functionality or pin arrangement.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts—TLV3704IPWR, MAX978EEE+, MAX993ESD+, MAX993ESD+T, MAX995ESD+, and MAX995ESD+T—are ROHS3 compliant with MSL Level 1 rating, matching the environmental compliance of the TLV3704IDR.

Q: What is the key limitation of MAX series comparators compared to TLV3704IDR?

A: The primary limitation is the restricted supply voltage range. MAX series devices operate from 2.5V to 5.5V (single supply) or ±1.25V to ±2.75V (dual supply), whereas TLV3704IDR supports 2.7V to 16V (single) or ±1.35V to ±8V (dual). Applications requiring higher supply voltages must use TLV3704IPWR or remain with TLV3704IDR inventory.

Q: Can I substitute TLV3704IDR in a design operating at 12V supply voltage?

A: TLV3704IPWR is the only substitute that supports 12V operation, as it maintains the full 2.7V to 16V supply range. MAX series comparators cannot be used at 12V supply voltage due to their 5.5V maximum rating.

Q: What packaging considerations should I evaluate when selecting a substitute?

A: TLV3704IPWR (14-TSSOP) requires PCB layout modification but offers thermal advantages. MAX993ESD+, MAX993ESD+T, MAX995ESD+, and MAX995ESD+T (14-SOIC) provide direct PCB compatibility without layout changes. MAX978EEE+ (16-SSOP) requires complete redesign and is not recommended for direct substitution.
