TLV2254AIPW Equivalent & Substitute Parts

Part Overview

The TLV2254AIPW is a general-purpose operational amplifier manufactured by Texas Instruments, featuring four independent circuits in a 14-TSSOP surface-mount package. This LinCMOS™ series device provides rail-to-rail output capability with low input bias current and is designed for applications requiring low-power, precision analog signal processing across industrial and consumer electronics.

The TLV2254AIPW maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified to support design flexibility, inventory optimization, and supply chain continuity when the primary part becomes unavailable or when application requirements necessitate alternative performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the TLV2254AIPW is determined by the following critical parameters:

Mechanical Compatibility:

• Package type: 14-TSSOP surface-mount package with 0.173" width (4.40mm)
• Mounting type: Surface mount
• Pin count and pinout: 14-pin configuration

Electrical Compatibility:

• Number of circuits: 4 independent amplifier circuits
• Output type: Rail-to-rail capability
• Supply voltage range: Minimum 2.7V, maximum 8V (or compatible subset)
• Operating temperature range: -40°C to 125°C (or compatible subset)

Regulatory Compliance:

• RoHS3 compliance required
• REACH unaffected status

The LMV324DTBR2G from onsemi satisfies all mechanical compatibility requirements and maintains the same 14-TSSOP package footprint. However, this substitute exhibits different electrical performance characteristics, including higher slew rate (1V/µs vs. 0.12V/µs), higher gain bandwidth product (1MHz vs. 200kHz), higher input bias current (1nA vs. 1pA), and reduced maximum supply voltage (5.5V vs. 8V). The operating temperature range is also narrower (-40°C to 85°C vs. -40°C to 125°C).

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (TLV2254AIPW): Select the TLV2254AIPW when applications require extended supply voltage operation up to 8V, extended operating temperature range to 125°C, or ultra-low input bias current (1pA). This part is suitable for battery-powered systems with wide voltage tolerance and industrial environments with elevated temperature requirements. Active product status and unlimited moisture sensitivity (MSL 1) provide superior handling flexibility during manufacturing and storage.

Substitute Part Selection (LMV324DTBR2G): The LMV324DTBR2G from onsemi is electrically compatible for applications operating within the reduced supply voltage range (2.7V to 5.5V) and temperature range (-40°C to 85°C). This substitute offers higher slew rate and gain bandwidth product, making it suitable for faster signal processing applications. Higher output current capability (160mA vs. 50mA per channel) supports higher-impedance load driving. However, the reduced maximum supply voltage and narrower temperature range must be verified against application requirements. Moisture sensitivity level 3 (168 hours) requires controlled storage and handling procedures.

Compliance Verification: Both parts maintain RoHS3 compliance and REACH unaffected status, satisfying regulatory requirements for EU and international markets. ECCN classification (EAR99) and HTSUS code (8542.33.0001) are identical, confirming export and tariff classification equivalence.

Frequently Asked Questions (FAQ)

Q: Can the LMV324DTBR2G directly replace the TLV2254AIPW in all applications?

A: Direct replacement is limited to applications operating within the LMV324DTBR2G specifications. The reduced maximum supply voltage (5.5V vs. 8V) and narrower operating temperature range (-40°C to 85°C vs. -40°C to 125°C) must be verified. Applications requiring the full 8V supply range or operation above 85°C cannot use this substitute without circuit redesign.

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

A: The LMV324DTBR2G provides significantly higher slew rate (1V/µs vs. 0.12V/µs) and gain bandwidth product (1MHz vs. 200kHz), enabling faster signal processing. However, it exhibits higher input offset voltage (1.7mV vs. 200µV) and higher input bias current (1nA vs. 1pA), which may affect precision analog applications. The LMV324DTBR2G offers higher output current per channel (160mA vs. 50mA).

Q: Are the packages mechanically identical?

A: Yes. Both parts use the 14-TSSOP surface-mount package with 0.173" width (4.40mm). Pinout and footprint are identical, allowing direct PCB layout compatibility without redesign.

Q: What is the impact of different moisture sensitivity levels?

A: The TLV2254AIPW (MSL 1) has unlimited shelf life and requires no special moisture control. The LMV324DTBR2G (MSL 3) requires storage below 30°C and 85% relative humidity, with a 168-hour floor life after bag opening. Manufacturing processes must include bake-out procedures before reflow soldering to prevent moisture-induced defects.

Q: Which part should be selected for new designs?

A: For new designs, select based on application requirements. The TLV2254AIPW is preferred for wide supply voltage range (up to 8V), extended temperature operation (to 125°C), and precision applications requiring ultra-low input bias current. The LMV324DTBR2G is suitable for applications requiring higher speed (slew rate and bandwidth) and higher output current within its specified voltage and temperature limits.

Q: Are there any supply chain considerations?

A: Current inventory shows 3088 units of TLV2254AIPW and 4035 units of LMV324DTBR2G in stock. Both parts maintain Active product status with established supply chains from their respective manufacturers.
