TLC2274MPWREP Equivalent & Substitute Parts

Part Overview

The TLC2274MPWREP is a general-purpose operational amplifier integrated circuit featuring four independent amplifier circuits in a 14-TSSOP surface mount package. This device is classified as obsolete, which necessitates identification of active equivalent alternatives for new designs and ongoing production requirements. The TLC2274MPWREP operates across a wide supply voltage range of 4.4V to 16V with rail-to-rail output capability, making it suitable for low-power analog signal processing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC2274MPWREP is determined by electrical and mechanical parameter equivalence across the following criteria:

Electrical Equivalence Requirements:

• Amplifier type: General Purpose
• Number of circuits: 4
• Output type: Rail-to-Rail
• Slew rate: 3.6 V/µs
• Gain bandwidth product: 2.25 MHz
• Input bias current: 1 pA
• Input offset voltage: 300 µV
• Supply current: 4.8 mA (x4 Channels)
• Output current per channel: 50 mA
• Supply voltage range: 4.4V to 16V minimum and maximum

Mechanical Equivalence Requirements:

• Package type: 14-TSSOP
• Package dimensions: 0.173" width, 4.40mm width
• Mounting type: Surface Mount

Compliance Requirements:

• RoHS3 compliance
• MSL rating: 1 (Unlimited)

The substitute parts TLC2274AIPWR and TLC2274IPWR satisfy all electrical and mechanical parameters. Both are active products manufactured by Texas Instruments with identical electrical specifications and package configurations. The primary distinction between the main part and substitutes is product status (obsolete versus active) and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The TLC2274MPWREP is classified as obsolete and should be replaced with an active equivalent for new designs and production continuity. Both TLC2274AIPWR and TLC2274IPWR are active products that provide complete electrical and mechanical compatibility with the TLC2274MPWREP.

Selection Basis:

The TLC2274AIPWR and TLC2274IPWR are direct functional equivalents with identical electrical performance across all specified parameters. Both devices maintain ROHS3 compliance and MSL rating 1 (Unlimited) classification. The primary technical difference is the operating temperature range: the TLC2274MPWREP operates from -55°C to 125°C, while both substitute parts operate from -40°C to 125°C. This narrower temperature range in the substitutes is acceptable for applications not requiring extended low-temperature operation below -40°C.

Both substitute parts are available in Cut Tape (CT) and Digi-Reel® packaging formats, supporting both prototype and production volume requirements. The TLC2274IPWR maintains significantly higher inventory availability (19,186 pieces) compared to TLC2274AIPWR (3,478 pieces), which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can TLC2274AIPWR and TLC2274IPWR be used interchangeably with TLC2274MPWREP?

A: Yes. Both substitute parts are electrically and mechanically equivalent to the TLC2274MPWREP across all specified parameters including slew rate, gain bandwidth product, supply voltage range, output current capability, and package configuration. The operating temperature range difference (-40°C to 125°C versus -55°C to 125°C) does not affect substitution for applications operating within the -40°C to 125°C window.

Q: What is the difference between TLC2274AIPWR and TLC2274IPWR?

A: Both parts are electrically identical with matching electrical specifications and package configurations. The primary distinction is inventory availability and packaging format options. TLC2274IPWR has higher stock levels (19,186 pieces) compared to TLC2274AIPWR (3,478 pieces). Both are available in Cut Tape (CT) and Digi-Reel® packaging.

Q: Is the operating temperature range difference significant for substitution?

A: The operating temperature range difference is relevant only for applications requiring operation below -40°C. The TLC2274MPWREP operates from -55°C to 125°C, while both substitutes operate from -40°C to 125°C. For applications operating within the -40°C to 125°C range, this difference does not affect device functionality or performance.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both TLC2274AIPWR and TLC2274IPWR are ROHS3 compliant and carry MSL rating 1 (Unlimited), matching the compliance status of the TLC2274MPWREP.

Q: What is the package compatibility between the main part and substitutes?

A: All three parts use identical 14-TSSOP surface mount packaging with 0.173" width and 4.40mm width dimensions. PCB footprints and assembly processes are directly compatible without modification.

Q: Why is the TLC2274MPWREP classified as obsolete?

A: The TLC2274MPWREP is an older product variant. Texas Instruments maintains active production of the TLC2274AIPWR and TLC2274IPWR variants, which provide identical electrical and mechanical functionality with current manufacturing support and availability.
