SN74LVC74APWR-P Equivalent & Substitute Parts

Part Overview

The SN74LVC74APWR-P is a dual D-type flip-flop logic integrated circuit manufactured by Texas Instruments. This device features two independent 1-bit D-type flip-flops with Set (Preset) and Reset functions, complementary outputs, and positive edge triggering. The component operates across a wide voltage supply range of 1.65V to 3.6V, making it suitable for low-voltage digital logic applications. With an active product status and ROHS3 compliance, the SN74LVC74APWR-P remains in production. Equivalent substitute parts are identified based on identical electrical performance specifications and mechanical compatibility within the 14-TSSOP package format.

Substitute Part Grouping Explanation

Substitute parts for the SN74LVC74APWR-P are identified based on strict parametric equivalence within the 74LVC74 logic family. All substitute candidates must satisfy the following criteria:

Critical Substitution Parameters:

• Base product number: 74LVC74
• Manufacturer: Texas Instruments
• Package type: 14-TSSOP (0.173", 4.40mm Width)
• Mounting type: Surface Mount
• Electrical specifications: Identical clock frequency (150 MHz), propagation delay (5.2ns @ 3.3V, 50pF), voltage supply range (1.65V ~ 3.6V), output current (24mA), and operating temperature range (-40°C ~ 125°C)
• Functional characteristics: Dual D-type flip-flops, complementary outputs, positive edge trigger, Set/Reset functions

The substitute parts differ only in packaging format (Tape & Reel or Tube) rather than electrical or mechanical specifications. These packaging variations do not affect component functionality or circuit performance.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SN74LVC74APWR-P, SN74LVC74APWT, and SN74LVC74APW—are functionally and electrically equivalent. Selection between these parts is determined by procurement and assembly requirements rather than technical performance criteria.

Selection Basis:

• SN74LVC74APWR-P (Tube packaging): Suitable for applications requiring individual component handling or lower-volume production runs. Tube packaging provides protection during manual assembly processes.

• SN74LVC74APWT (Tape & Reel packaging): Optimized for high-volume automated assembly operations. Tape & Reel format integrates directly with pick-and-place equipment, reducing handling time and improving production efficiency.

• SN74LVC74APW (Tube packaging): Alternative tube-packaged option with identical electrical specifications and mechanical compatibility.

All parts maintain Active product status with ROHS3 compliance and MSL Level 1 (Unlimited moisture sensitivity), ensuring long-term availability and environmental regulatory compliance. Component selection should align with manufacturing process capabilities and supply chain logistics.

Frequently Asked Questions (FAQ)

Q: Can SN74LVC74APWT be used as a direct replacement for SN74LVC74APWR-P in circuit design?

A: Yes. Both parts are electrically and functionally identical. The only difference is packaging format (Tape & Reel versus Tube). Circuit performance, pin configuration, electrical characteristics, and operating parameters are identical. Substitution is valid for any application using the SN74LVC74APWR-P.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging contains individual components in a protective plastic tube, suitable for manual assembly and lower-volume production. Tape & Reel packaging places components on a continuous carrier tape wound on a reel, designed for automated pick-and-place assembly equipment. Both formats contain the same component with identical specifications.

Q: Are all three parts (SN74LVC74APWR-P, SN74LVC74APWT, SN74LVC74APW) pin-compatible?

A: Yes. All three parts use the 14-TSSOP package with identical pin assignments, pin spacing (0.173" width, 4.40mm), and pin functions. Pin-to-pin compatibility is complete.

Q: Does packaging format affect electrical performance or reliability?

A: No. Packaging format does not affect electrical performance, propagation delay, clock frequency, voltage supply range, output current, or operating temperature range. All electrical and reliability characteristics remain identical across all three part numbers.

Q: Which substitute part should be selected for high-volume manufacturing?

A: SN74LVC74APWT (Tape & Reel format) is optimized for high-volume automated assembly. This packaging format integrates with standard pick-and-place equipment, reducing assembly time and labor costs.

Q: Are there any compliance or regulatory differences between the three parts?

A: No. All three parts maintain identical RoHS3 compliance, MSL Level 1 (Unlimited), and Active product status. Regulatory and environmental compliance is equivalent across all substitute options.

Q: Can SN74LVC74APW be substituted for SN74LVC74APWR-P?

A: Yes. SN74LVC74APW is a direct electrical and functional equivalent. Both use Tube packaging and are interchangeable in circuit applications. Selection between them depends on inventory availability and supply chain preferences.
