TLV3702ID Equivalent & Substitute Parts

Part Overview

The TLV3702ID is a general-purpose dual comparator IC manufactured by Texas Instruments, featuring CMOS push-pull rail-to-rail output architecture in an 8-SOIC surface mount package. This device operates across a wide supply voltage range of 2.7V to 16V (single supply) or ±1.35V to ±8V (dual supply), with low input offset voltage and minimal quiescent current consumption.

The TLV3702ID is classified as obsolete. Equivalent and substitute parts are necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements. Substitute devices must maintain functional compatibility across electrical performance, package form factor, and operating temperature specifications.

Engineering Selection Recommendations

Primary Recommendation: TLV3702IDR

TLV3702IDR is the direct active equivalent to TLV3702ID. It maintains identical electrical specifications, supply voltage range, and operating temperature performance. Both devices are ROHS3 compliant with MSL 1 rating. The only difference is packaging format (Cut Tape & Digi-Reel versus Tube) and active product status. This part provides seamless design continuity with no circuit modifications required.

Secondary Recommendation: LTC6702HDC#TRMPBF or LTC6702HTS8#TRMPBF

These Analog Devices comparators support the full -40°C ~ 125°C operating temperature range matching TLV3702ID. However, the supply voltage range is restricted to 1.7V ~ 5.5V, limiting applicability to designs operating within this envelope. Package options include 8-DFN (2x2) and TSOT-23-8. Both are ROHS3 compliant with MSL 1 rating and active product status.

Conditional Recommendation: ALD2332ASAL or ALD2332BSAL

Advanced Linear Devices ALD2332 series offers enhanced input offset voltage performance (0.5mV to 1mV) and includes CMRR/PSRR specifications (80dB/75dB). However, operating temperature is limited to 0°C ~ 70°C and supply voltage range is 4V ~ 10V. These parts are suitable only for applications within these restricted parameters. Both are ROHS3 compliant with MSL 1 rating and active product status.

Not Recommended: ALD2302 Series and LTC6702 Standard Temperature Variants

ALD2302ASAL and ALD2302SAL are restricted to 0°C ~ 70°C operating temperature and 4V ~ 10V supply range, making them unsuitable for industrial temperature applications. LTC6702CDC#TRPBF, LTC6702CTS8#TRPBF, and LTC6702CTS8#TRMPBF are limited to 0°C ~ 70°C operation and 1.7V ~ 5.5V supply voltage, restricting their use to consumer and commercial temperature grades.

Frequently Asked Questions (FAQ)

Q: Can TLV3702IDR be used as a direct replacement for TLV3702ID?

A: Yes. TLV3702IDR is the active equivalent with identical electrical specifications, supply voltage range (2.7V ~ 16V single, ±1.35V ~ 8V dual), and operating temperature (-40°C ~ 125°C). The only difference is packaging format. No circuit modifications are required.

Q: What is the key limitation of ALD2332 and ALD2302 series comparators?

A: Both ALD2332 and ALD2302 series are restricted to 0°C ~ 70°C operating temperature and 4V ~ 10V supply voltage range. They cannot be used in applications requiring -40°C ~ 125°C industrial temperature operation or supply voltages above 10V.

Q: Can LTC6702 devices replace TLV3702ID in all applications?

A: LTC6702 devices have a restricted supply voltage range of 1.7V ~ 5.5V compared to TLV3702ID's 2.7V ~ 16V range. Standard temperature variants (LTC6702CDC, LTC6702CTS8) operate only to 70°C. Extended temperature variants (LTC6702HDC#TRMPBF, LTC6702HTS8#TRMPBF) support -40°C ~ 125°C but still require supply voltages within 1.7V ~ 5.5V. Substitution is valid only when circuit supply voltages fall within this range.

Q: What package options are available for TLV3702 substitutes?

A: Substitute parts are available in three package formats: 8-SOIC (0.154" width), 8-DFN (2x2 with exposed pad), and TSOT-23-8 (thin profile). All are surface mount configurations with identical pin counts. PCB layout modifications may be required when changing package types.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance status and MSL 1 (unlimited moisture sensitivity level) rating, matching the original TLV3702ID specifications.

Q: What is the difference between ALD2332ASAL and ALD2332BSAL?

A: Both are EPAD series comparators with identical electrical performance except for input offset voltage: ALD2332ASAL specifies 0.5mV maximum at 5V, while ALD2332BSAL specifies 1mV maximum at 5V. Both operate at 0°C ~ 70°C with 4V ~ 10V supply range and are not suitable for full industrial temperature applications.

Q: Can I use LTC6702CTS8 variants in place of 8-SOIC packaged devices?

A: LTC6702CTS8 uses TSOT-23-8 package instead of 8-SOIC. While pin count is identical, the physical footprint differs significantly. PCB redesign is required. Additionally, supply voltage is limited to 1.7V ~ 5.5V and standard temperature variants operate only to 70°C.
