Engineering Selection Recommendations

Direct Replacement (Identical Electrical Performance):

TLC274CPWR is the recommended primary substitute. This part maintains identical electrical specifications to the TLC274CPWRG4, including slew rate, gain bandwidth product, supply current, and output current ratings. Both parts are general-purpose amplifiers with matching performance characteristics. TLC274CPWR holds active product status with 4300 pieces in stock, ensuring production continuity. Both parts are ROHS3 compliant and carry identical compliance certifications.

Performance-Enhanced Alternatives (Higher Performance Capability):

TS274IPT provides enhanced performance with 5.5 V/µs slew rate and 3.5 MHz gain bandwidth product, exceeding the original specification. This part operates across an extended temperature range (-40°C to 125°C) and is ROHS3 compliant. TS274IPT is suitable for applications requiring higher bandwidth or wider operating temperature specifications.

Low-Power Alternatives (Reduced Supply Current):

TS27L4IPT, TS27L4AIPT, TS27L4CPT, and TS27L4ACPT are low-power CMOS variants with supply current of 10 µA per 4-channel configuration, compared to 2.7 mA for the original part. These alternatives are appropriate for battery-powered or low-power applications where reduced quiescent current is required. TS27L4IPT and TS27L4AIPT support extended temperature ranges (-40°C to 125°C).

Intermediate Performance Alternative:

TS27M4CPT offers moderate performance with 0.6 V/µs slew rate and 1 MHz gain bandwidth product, with supply current of 150 µA. This part provides a balance between the low-power TS27L4 series and the higher-performance TS274IPT.

All substitute parts maintain the 14-TSSOP package configuration, 4-circuit amplifier topology, and 3 V to 16 V supply voltage range required for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can TLC274CPWR directly replace TLC274CPWRG4 without circuit modification?

A: Yes. TLC274CPWR is the active equivalent with identical electrical specifications, package configuration, and pin assignment. No circuit modifications are required for direct substitution.

Q: What is the difference between the TLC274CPWRG4 and TS274IPT?

A: Both are 4-circuit operational amplifiers in 14-TSSOP packages with compatible supply voltage ranges. TS274IPT is a CMOS technology variant with higher slew rate (5.5 V/µs vs. 3.6 V/µs), higher gain bandwidth product (3.5 MHz vs. 2.2 MHz), lower supply current (1 mA vs. 2.7 mA), and extended operating temperature range (-40°C to 125°C vs. 0°C to 70°C). TS274IPT is suitable for applications requiring enhanced performance or wider temperature operation.

Q: When should I use the TS27L4 series instead of the TLC274CPWRG4?

A: The TS27L4 series (TS27L4IPT, TS27L4AIPT, TS27L4CPT, TS27L4ACPT) is appropriate when low quiescent current consumption is critical. These parts draw only 10 µA supply current compared to 2.7 mA for the TLC274CPWRG4. However, the TS27L4 series has significantly lower slew rate (0.04 V/µs) and gain bandwidth product (100 kHz), making them unsuitable for high-speed applications. Selection depends on application bandwidth requirements versus power consumption constraints.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (TLC274CPWR, TS274IPT, TS27L4ACPT, TS27L4AIPT, TS27L4CPT, TS27L4IPT, TS27M4CPT) are ROHS3 compliant with moisture sensitivity level 1 (unlimited).

Q: What is the difference between TS27L4IPT and TS27L4AIPT?

A: Both parts are identical CMOS low-power amplifiers with 0.04 V/µs slew rate and 100 kHz gain bandwidth product. The primary difference is operating temperature range: TS27L4IPT operates from -40°C to 125°C, while TS27L4AIPT also operates from -40°C to 125°C. Both support extended temperature operation compared to the original TLC274CPWRG4 (0°C to 70°C).

Q: Can I use TS27M4CPT as a direct replacement?

A: TS27M4CPT maintains package compatibility and supply voltage range but has reduced slew rate (0.6 V/µs vs. 3.6 V/µs) and lower gain bandwidth product (1 MHz vs. 2.2 MHz). It is suitable only for applications with bandwidth requirements below 1 MHz. For general-purpose applications matching the original specification, TLC274CPWR or TS274IPT are more appropriate.

Q: What packaging options are available for substitute parts?

A: All substitute parts are supplied in 14-TSSOP surface mount packages. TLC274CPWR is available in Cut Tape (CT) and Digi-Reel® packaging. TS274IPT, TS27L4ACPT, TS27L4AIPT, TS27L4CPT, TS27L4IPT, and TS27M4CPT are available in Tape & Reel (TR) packaging. Verify packaging requirements with your procurement specifications.
