TLC2274IPWRG4 Equivalent & Substitute Parts

Part Overview

The TLC2274IPWRG4 is a general-purpose operational amplifier featuring four independent circuits in a 14-TSSOP surface-mount package. This device provides rail-to-rail output capability with a supply voltage range of 4.4 V to 16 V and operates across the industrial temperature range of -40°C to 125°C. The TLC2274IPWRG4 is classified as obsolete, necessitating identification of active equivalent and substitute components for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC2274IPWRG4 is determined by the following critical parameters:

Primary Substitution Criteria:

• Amplifier type: General Purpose
• Number of circuits: 4 independent channels
• Output configuration: Rail-to-rail
• Package type: 14-TSSOP surface mount
• Supply voltage range: Minimum 4.4 V to maximum 16 V
• Operating temperature range: -40°C to 125°C
• RoHS3 compliance and MSL Level 1 rating

Substitute parts must maintain identical or superior electrical performance within these constraints and must be available in the same 14-TSSOP package configuration. The TLC2274IPWR (Texas Instruments) and AD8668ARUZ (Analog Devices Inc.) satisfy these core substitution requirements while offering active product status.

Engineering Selection Recommendations

TLC2274IPWR (Texas Instruments)

The TLC2274IPWR is the direct manufacturer-recommended substitute for the obsolete TLC2274IPWRG4. This part maintains identical electrical specifications across all critical parameters, including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and output current per channel. The TLC2274IPWR is classified as active product status and carries ROHS3 compliance with MSL Level 1 rating. This substitute is available in Cut Tape and Digi-Reel packaging formats with higher inventory availability (19,186 units in stock). Selection of the TLC2274IPWR is appropriate for direct replacement applications requiring no circuit redesign.

AD8668ARUZ (Analog Devices Inc.)

The AD8668ARUZ is an alternative substitute offering enhanced performance characteristics in specific parameters. This device provides superior gain bandwidth product (4 MHz versus 2.25 MHz), lower input bias current (0.2 pA versus 1 pA), and significantly higher output current per channel (140 mA versus 50 mA). The AD8668ARUZ operates with reduced supply current consumption (1.15 mA versus 4.8 mA across four channels), resulting in lower power dissipation. The minimum supply voltage requirement is 5 V compared to 4.4 V for the TLC2274 series. The AD8668ARUZ is classified as active product status with ROHS3 compliance and MSL Level 1 rating. This substitute is suitable for applications requiring enhanced bandwidth, lower power consumption, or higher output drive capability, provided the 5 V minimum supply voltage requirement is compatible with the circuit design.

Frequently Asked Questions (FAQ)

Q: Can the TLC2274IPWR be used as a direct replacement for the TLC2274IPWRG4?

A: Yes. The TLC2274IPWR is the manufacturer-recommended substitute with identical electrical specifications and package configuration. No circuit modifications are required for direct substitution.

Q: What is the primary difference between the TLC2274IPWR and AD8668ARUZ?

A: The AD8668ARUZ offers higher gain bandwidth product (4 MHz versus 2.25 MHz), lower input bias current (0.2 pA versus 1 pA), higher output current per channel (140 mA versus 50 mA), and lower supply current consumption (1.15 mA versus 4.8 mA). The AD8668ARUZ requires a minimum supply voltage of 5 V, whereas the TLC2274 series operates at 4.4 V minimum.

Q: Are all substitute parts available in the same 14-TSSOP package?

A: Yes. Both the TLC2274IPWR and AD8668ARUZ are packaged in 14-TSSOP (0.173", 4.40mm Width) surface-mount configuration, ensuring mechanical and electrical compatibility with existing PCB layouts.

Q: Do the substitute parts meet RoHS and MSL requirements?

A: Yes. Both the TLC2274IPWR and AD8668ARUZ are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited) rating, matching the compliance profile of the original TLC2274IPWRG4.

Q: Which substitute should be selected for power-sensitive applications?

A: The AD8668ARUZ is recommended for power-sensitive applications due to its significantly lower supply current consumption (1.15 mA versus 4.8 mA across four channels), resulting in reduced power dissipation and extended battery life in portable applications.

Q: What is the impact of the AD8668ARUZ minimum supply voltage requirement of 5 V?

A: The AD8668ARUZ minimum supply voltage of 5 V is 0.6 V higher than the TLC2274 series minimum of 4.4 V. Applications operating at supply voltages below 5 V must use the TLC2274IPWR to ensure proper device operation.

Q: Can the AD8668ARUZ be used in applications requiring the full 4.4 V minimum supply voltage?

A: No. The AD8668ARUZ minimum supply voltage specification of 5 V precludes its use in applications requiring operation at 4.4 V. The TLC2274IPWR must be selected for such applications.
