TLV3704CD Equivalent & Substitute Parts

Part Overview

The TLV3704CD is a general-purpose CMOS comparator IC manufactured by Texas Instruments, featuring four independent comparators in a 14-SOIC surface-mount package. This device operates across a wide supply voltage range (2.5V to 16V single supply, ±1.25V to ±8V dual supply) with rail-to-rail push-pull CMOS output architecture. The TLV3704CD is designated as Last Time Buy, indicating end-of-life status. Equivalent and substitute parts are necessary to ensure design continuity and maintain component availability for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLV3704CD are classified based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Number of comparator elements: 4 (mandatory)
• Output type: CMOS, Push-Pull, Rail-to-Rail (core functionality requirement)
• Supply voltage range overlap with 2.5V ~ 16V single supply capability
• Input offset voltage specification: 5mV or better
• Input bias current specification: 250pA or better
• Quiescent current specification: 1µA or better
• RoHS3 compliance and EAR99 classification

Grouping Logic:

Group 1 - Direct Package Equivalents (14-SOIC): Parts maintaining identical 14-SOIC packaging with matching electrical specifications. These provide pin-for-pin compatibility with minimal PCB redesign.

Group 2 - Package Variants (14-TSSOP, 14-DIP): Parts with identical electrical performance but different package footprints. These require PCB layout modification but maintain functional equivalence.

Group 3 - Enhanced Performance Variants (16-SOIC, 16-QSOP): Parts with superior electrical characteristics (lower propagation delay, improved CMRR/PSRR, extended temperature range) but different package configurations and pin counts.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Minimum Redesign):

TLV3704IPWR is the primary recommended substitute. Manufactured by Texas Instruments with Active product status, this part maintains the same base product architecture (TLV3704) with identical electrical specifications. The 14-TSSOP package requires PCB footprint modification but eliminates design risk associated with cross-manufacturer substitution. Extended operating temperature range (-40°C to 125°C) provides enhanced reliability margin compared to the original 0°C to 70°C specification.

For Cost-Optimized Designs (Supply Voltage ≤ 5.5V):

MAX993ESD+T and MAX995ESD+T offer Active product status with identical 14-SOIC packaging, eliminating PCB redesign requirements. Both parts maintain 5mV input offset specification and superior input bias current (1pA). Selection between these variants depends on quiescent current requirements: MAX993ESD+T at 24µA or MAX995ESD+T at 96µA. These parts are suitable only for applications operating within the 2.5V to 5.5V supply range.

For Enhanced Performance Applications:

MAX978ESE+T provides superior electrical characteristics (2mV input offset, 28ns propagation delay, 4mV hysteresis) in 16-SOIC packaging. This variant requires PCB redesign due to 16-pin configuration but delivers improved signal integrity for precision measurement applications. Extended temperature range (-40°C to 85°C) supports industrial deployment.

For Through-Hole Assembly:

ALD4302APBL by Advanced Linear Devices Inc. offers 14-DIP through-hole packaging for legacy PCB designs. This part maintains Active status and identical element count. Supply voltage range restriction (4V to 10V) and elevated quiescent current (1mA) limit applicability to designs operating within these constraints.

Compliance Verification:

All recommended substitutes maintain ROHS3 compliance, EAR99 classification, and unlimited moisture sensitivity level (MSL 1), ensuring regulatory and supply chain compatibility with the original TLV3704CD specification.

Frequently Asked Questions (FAQ)

Q: Can TLV3704IPWR replace TLV3704CD without PCB modification?

A: TLV3704IPWR uses 14-TSSOP packaging versus the original 14-SOIC. While both are 14-pin surface-mount packages, the pin pitch and footprint differ, requiring PCB layout modification. Electrical specifications are compatible.

Q: What is the key limitation when substituting with MAX993ESD+T or MAX995ESD+T?

A: These Maxim parts operate within 2.5V to 5.5V supply range, compared to the TLV3704CD's 2.5V to 16V capability. Substitution is valid only for designs operating at 5.5V or below. Applications requiring higher supply voltages must use TLV3704IPWR or MAX978 series variants.

Q: Why does ALD4302APBL have higher quiescent current (1mA) than the original (1µA)?

A: The ALD4302APBL is a different device architecture from Advanced Linear Devices Inc. with different internal design. While it maintains four comparators and general-purpose functionality, the elevated quiescent current reflects different circuit topology and is a trade-off for through-hole packaging availability.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and EAR99 classification, matching the original TLV3704CD regulatory status.

Q: What is the difference between MAX978EEE+T and MAX978ESE+T?

A: MAX978EEE+T uses 16-QSOP packaging (0.154" width), while MAX978ESE+T uses 16-SOIC packaging (0.154" width). Electrical specifications are identical. Package selection depends on PCB layout constraints and assembly equipment capability.

Q: Can I use MAX978 series parts as direct pin-for-pin replacements?

A: No. MAX978 series parts feature 16-pin configuration versus the 14-pin TLV3704CD. PCB redesign is required. However, these parts offer superior electrical performance (2mV input offset, 28ns propagation delay) for applications where performance enhancement justifies redesign effort.

Q: Which substitute offers the best low-power performance?

A: TLV3704IPWR maintains the original 1µA quiescent current specification, providing optimal low-power operation. MAX993ESD+T at 24µA and MAX995ESD+T at 96µA consume more power but offer superior input bias current (1pA) for high-impedance signal applications.
