SN74LVC2G74YEAR Equivalent & Substitute Parts

Part Overview

The SN74LVC2G74YEAR is a single D-type flip-flop logic integrated circuit manufactured by Texas Instruments, housed in an 8-XFBGA, DSBGA surface mount package. This device functions as a 1-bit, 1-element flip-flop with complementary outputs, set/preset and reset capabilities, and positive edge triggering. The part is currently listed as obsolete, making identification of equivalent and substitute components essential for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution for the SN74LVC2G74YEAR is determined by strict equivalence across the following critical parameters:

Base product number (74LVC2G74)
Functional architecture (single D-type flip-flop, 1 element, 1 bit)
Output configuration (complementary outputs)
Trigger mechanism (positive edge)
Electrical specifications (clock frequency, propagation delay, voltage supply range, output current, quiescent current)
Operating temperature range (-40°C ~ 85°C)
Surface mount packaging (8-XFBGA, DSBGA)
Compliance certifications (ROHS3, REACH Unaffected)

The SN74LVC2G74YZPR is identified as a parametric equivalent based on identical functional and electrical characteristics. The primary distinction is product status and packaging configuration (Tape & Reel vs. standard packaging), with the substitute part currently in active production status.

Engineering Selection Recommendations

The SN74LVC2G74YZPR is the direct parametric equivalent for the obsolete SN74LVC2G74YEAR. Selection of the substitute part is supported by the following factors:

Identical electrical and functional specifications across all critical parameters
Active production status ensures ongoing availability and supply chain continuity
ROHS3 compliance and REACH Unaffected status maintain regulatory alignment
Tape & Reel packaging configuration is standard for high-volume production environments
No design modifications or circuit re-qualification are required for direct substitution

The primary consideration is packaging format. The SN74LVC2G74YZPR is supplied in Tape & Reel configuration, which is the industry standard for automated assembly. Organizations requiring alternative packaging formats should consult Texas Instruments product documentation for additional package options within the 74LVC2G74 base product family.

Frequently Asked Questions (FAQ)

Q: Can the SN74LVC2G74YZPR be used as a direct replacement for the SN74LVC2G74YEAR?

A: Yes. The SN74LVC2G74YZPR is a parametric equivalent with identical electrical specifications, functional architecture, and package dimensions. No circuit modifications are required.

Q: What is the difference between the two part numbers?

A: The primary differences are product status and packaging configuration. The SN74LVC2G74YEAR is obsolete and supplied in standard packaging, while the SN74LVC2G74YZPR is in active production and supplied in Tape & Reel format. All electrical and functional parameters are identical.

Q: Are there any compatibility concerns with the 8-XFBGA, DSBGA package?

A: No. Both parts use the same 8-XFBGA, DSBGA surface mount package with identical pinout and mechanical dimensions. PCB footprints and assembly processes remain unchanged.

Q: Does the Tape & Reel packaging affect circuit performance?

A: No. Tape & Reel is a supply and handling format only. It does not affect the electrical characteristics, performance, or reliability of the component once assembled onto the PCB.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the SN74LVC2G74YEAR and SN74LVC2G74YZPR are ROHS3 compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
