TLV274IPWR Equivalent & Substitute Parts

Part Overview

The TLV274IPWR is a general-purpose operational amplifier manufactured by Texas Instruments, featuring four independent amplifier circuits in a 14-TSSOP surface-mount package. This rail-to-rail output device operates across a 2.7V to 16V supply range and is designed for applications requiring low-power, precision analog signal processing. The part is currently in active production status with substantial inventory availability. Substitute parts are identified when equivalent functional performance can be achieved within the specified electrical and mechanical parameters while maintaining package compatibility and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLV274IPWR is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 14-TSSOP surface-mount package with identical physical dimensions (0.173", 4.40mm Width) to ensure PCB layout compatibility without redesign.

Functional Equivalence: The substitute must provide four independent general-purpose amplifier circuits with rail-to-rail output capability.

Electrical Operating Range: The substitute supply voltage range must encompass or exceed the minimum 2.7V and maximum 16V specification of the main part to ensure operation across all intended applications.

Temperature Rating: The substitute must support the full -40°C to 125°C operating temperature range.

Compliance Standards: Both parts must maintain ROHS3 compliance and MSL Level 1 rating to meet manufacturing and environmental requirements.

The TLV274DTBR2G from onsemi meets all substitution criteria within these parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (TLV274IPWR): Use the Texas Instruments TLV274IPWR when the application requires the specified electrical characteristics, including the 2.7V to 16V supply range, 550µA total supply current, and 8mA output current per channel. This part is in active production with high inventory availability and meets all ROHS3 and MSL requirements.

Substitute Selection (TLV274DTBR2G): The onsemi TLV274DTBR2G serves as a functional substitute when supply chain constraints or lead-time requirements necessitate an alternative source. This part maintains identical package geometry, circuit count, and output type. The onsemi variant offers an extended maximum supply voltage of 36V (versus 16V for the primary part), lower total supply current (465µA versus 550µA), and higher output current capability (65mA per channel versus 8mA). The onsemi part includes AEC-Q100 automotive qualification, which may be relevant for applications requiring automotive-grade components. Both parts maintain ROHS3 compliance and MSL Level 1 rating.

Compliance Verification: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS coding (8542.33.0001), confirming regulatory equivalence for procurement and export purposes.

Frequently Asked Questions (FAQ)

Q: Can the TLV274DTBR2G directly replace the TLV274IPWR on an existing PCB?

A: Yes. Both parts use identical 14-TSSOP surface-mount packages with matching pin configurations and physical dimensions (0.173", 4.40mm Width). No PCB layout modifications are required for mechanical or electrical connectivity.

Q: What are the key electrical differences between these two parts?

A: The primary differences are: (1) Maximum supply voltage is 36V for the onsemi part versus 16V for the Texas Instruments part; (2) Total supply current is 465µA (onsemi) versus 550µA (Texas Instruments); (3) Output current per channel is 65mA (onsemi) versus 8mA (Texas Instruments); (4) Input bias current is 5pA (onsemi) versus 1pA (Texas Instruments); (5) Input offset voltage is 1.3mV (onsemi) versus 500µV (Texas Instruments). Both parts share identical 3MHz gain-bandwidth product and support the full -40°C to 125°C temperature range.

Q: Are there any compliance or certification differences?

A: The onsemi TLV274DTBR2G includes AEC-Q100 automotive qualification, while the Texas Instruments TLV274IPWR does not specify automotive grading. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (Unlimited) moisture sensitivity ratings. Regulatory classification (ECCN EAR99, HTSUS 8542.33.0001) is identical.

Q: Which part should be selected for applications requiring maximum output current?

A: The onsemi TLV274DTBR2G provides 65mA per channel output current, compared to 8mA per channel for the Texas Instruments part. Applications requiring higher output drive capability should specify the onsemi variant.

Q: Is the extended supply voltage range of the onsemi part a concern for 16V maximum applications?

A: No. The onsemi part's 36V maximum rating does not affect operation at 16V or below. The 2.7V minimum supply voltage is identical for both parts, ensuring compatibility across the full intended operating range of the primary part.

Q: What packaging formats are available for these parts?

A: The TLV274IPWR is supplied in Cut Tape (CT) and Digi-Reel® formats. The TLV274DTBR2G is supplied in Tape & Reel (TR) format. Both use the same 14-TSSOP package; packaging format selection depends on assembly process requirements and order quantities.
