TLC274CPWR Equivalent & Substitute Parts

Part Overview

The TLC274CPWR is a general purpose operational amplifier integrated circuit manufactured by Texas Instruments, configured as a 4-circuit device in a 14-TSSOP surface mount package. This component is classified as a linear amplifier and maintains Active product status with full RoHS3 compliance. The TLC274CPWR serves applications requiring low-power, general-purpose amplification across industrial, consumer, and embedded system designs. Identifying equivalent and substitute parts becomes necessary when addressing supply chain constraints, inventory availability, or specific application performance requirements while maintaining functional compatibility within the 14-TSSOP package footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLC274CPWR is determined by strict adherence to the following critical parameters:

Package Compatibility: All substitute parts must use the 14-TSSOP surface mount package with identical 0.173" (4.40mm) width specification to ensure mechanical and electrical compatibility on printed circuit boards.

Circuit Configuration: Substitute parts must contain exactly 4 operational amplifier circuits to match the quad-channel architecture of the TLC274CPWR.

Supply Voltage Range: The substitute part must operate within or encompass the TLC274CPWR supply voltage range of 3V to 16V minimum to maximum. Parts with extended supply ranges remain compatible provided the minimum threshold does not exceed 3V and the maximum does not fall below 16V.

Mounting Technology: Surface mount technology is mandatory; through-hole or other mounting types are not acceptable substitutes.

Compliance Standards: All substitute parts must maintain RoHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating to ensure regulatory and manufacturing process compatibility.

Amplifier Classification: Substitute parts must be classified as operational amplifiers within the Linear, Amplifiers category.

The following parts meet these substitution criteria: NCS20074DTBR2G (onsemi) and TS27L4IPT (STMicroelectronics).

Parameter Comparison

Engineering Selection Recommendations

NCS20074DTBR2G (onsemi): This substitute part maintains Active product status and full RoHS3 compliance identical to the TLC274CPWR. The NCS20074DTBR2G operates within an extended supply voltage range (2.7V to 36V) that encompasses the TLC274CPWR specification window. The part features rail-to-rail output capability and demonstrates higher output current per channel (65 mA versus 30 mA). The NCS20074DTBR2G exhibits lower supply current consumption (420µA total versus 2.7mA) and supports an extended operating temperature range (-40°C to 125°C versus 0°C to 70°C). Slew rate is reduced to 2.4V/µs, while gain bandwidth product increases to 3.2 MHz. This substitute is suitable for applications where extended temperature operation, reduced power consumption, or higher output drive capability is beneficial.

TS27L4IPT (STMicroelectronics): This substitute part maintains Active product status and full RoHS3 compliance. The TS27L4IPT is classified as a CMOS amplifier and operates within the identical supply voltage range (3V to 16V) as the TLC274CPWR. The part demonstrates significantly reduced supply current consumption (10µA total versus 2.7mA) and supports an extended operating temperature range (-40°C to 125°C versus 0°C to 70°C). However, the TS27L4IPT exhibits substantially reduced slew rate (0.04V/µs versus 3.6V/µs) and gain bandwidth product (100 kHz versus 2.2 MHz). This substitute is appropriate for low-frequency, ultra-low-power applications where bandwidth and slew rate requirements are minimal.

Frequently Asked Questions (FAQ)

Q: Can the NCS20074DTBR2G directly replace the TLC274CPWR in all applications?

A: The NCS20074DTBR2G meets all mandatory substitution criteria: identical 14-TSSOP package, 4-circuit configuration, compatible supply voltage range, and equivalent compliance certifications. However, performance characteristics differ. The NCS20074DTBR2G provides higher gain bandwidth product (3.2 MHz versus 2.2 MHz) and lower supply current (420µA versus 2.7mA). Applications sensitive to slew rate or bandwidth specifications must verify compatibility with the reduced slew rate of 2.4V/µs.

Q: Is the TS27L4IPT suitable for high-speed signal processing applications?

A: The TS27L4IPT is not suitable for high-speed applications. The part exhibits a gain bandwidth product of 100 kHz and slew rate of 0.04V/µs, compared to the TLC274CPWR specifications of 2.2 MHz and 3.6V/µs respectively. The TS27L4IPT is designed for low-frequency, ultra-low-power applications only.

Q: Do all three parts share identical pinout compatibility?

A: All three parts use the 14-TSSOP package with 0.173" (4.40mm) width. Pinout compatibility must be verified against specific application schematics and PCB layouts, as package designation alone does not guarantee identical pin assignments across different manufacturers.

Q: What is the significance of the rail-to-rail output feature in the NCS20074DTBR2G?

A: Rail-to-rail output capability allows the NCS20074DTBR2G output voltage to swing closer to the positive and negative supply rails compared to the TLC274CPWR. This feature increases usable output voltage range and is beneficial in low-supply-voltage applications or when maximum signal swing is required.

Q: Are there temperature range limitations when substituting the TLC274CPWR?

A: The TLC274CPWR operates from 0°C to 70°C. Both substitute parts (NCS20074DTBR2G and TS27L4IPT) support extended temperature ranges (-40°C to 125°C). Applications operating within the TLC274CPWR temperature window remain compatible with either substitute. Applications requiring operation below 0°C or above 70°C must use one of the substitute parts.

Q: How does supply current consumption affect circuit design when substituting parts?

A: The TLC274CPWR draws 2.7mA total supply current. The NCS20074DTBR2G draws 420µA, and the TS27L4IPT draws 10µA. Lower supply current reduces power dissipation and thermal load. Designs with tight power budgets or thermal constraints may benefit from the lower-consumption substitutes. Conversely, designs with existing power supply capacity may not require modification.

Q: What compliance certifications are maintained across all three parts?

A: All three parts maintain RoHS3 compliance, MSL Level 1 (Unlimited) moisture sensitivity rating, and Active product status. REACH status is Unaffected for all parts. ECCN classification is EAR99 for all parts. HTSUS code 8542.33.0001 applies to all parts.
