Substitute Part Grouping Explanation

Substitute parts for the 74ALVC374PW,112 are identified based on strict electrical and mechanical compatibility criteria. The following parameters determine valid substitution:

• Functional Type: D-Type flip-flop with 1 element and 8 bits per element
• Output Configuration: Tri-state, non-inverted outputs
• Trigger Mechanism: Positive edge triggering
• Supply Voltage Range: 1.65V ~ 3.6V (must encompass or match the original specification)
• Output Drive Capability: 24mA high and low current
• Package Format: 20-TSSOP surface mount package with identical physical dimensions
• Operating Temperature Range: -40°C ~ 85°C
• Compliance Standards: ROHS3 compliant, REACH unaffected

The identified substitute parts (SN74ALVCH374PW and SN74ALVCH374PWR) maintain functional equivalence across all critical parameters while differing in packaging format (Tube vs. Tape & Reel) and product status (Active vs. Obsolete).

Parameter Comparison

Engineering Selection Recommendations

Both SN74ALVCH374PW and SN74ALVCH374PWR from Texas Instruments serve as direct functional equivalents to the obsolete 74ALVC374PW,112. Selection between these alternatives should be based on procurement and supply chain requirements:

SN74ALVCH374PW (Tube Packaging): Suitable for lower-volume applications, prototype development, and situations requiring individual component handling. This packaging format provides flexibility for small-batch assembly operations.

SN74ALVCH374PWR (Tape & Reel Packaging): Recommended for high-volume production environments where automated pick-and-place assembly is employed. This format optimizes manufacturing throughput and reduces handling costs in mass production scenarios.

Both substitute parts maintain active product status with Texas Instruments, ensuring long-term availability and continued technical support. Both comply with ROHS3 and REACH requirements, matching the compliance profile of the original component. The clock frequency specification differs (150 MHz vs. 300 MHz), but this represents a conservative design margin that does not restrict functional substitution in applications designed for the original 74ALVC374PW,112 specifications.

Frequently Asked Questions (FAQ)

Q: Can SN74ALVCH374PW and SN74ALVCH374PWR be used interchangeably in the same circuit?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Tube vs. Tape & Reel). Selection depends on assembly method and procurement volume, not circuit performance.

Q: What is the significance of the clock frequency difference (300 MHz vs. 150 MHz)?

A: The original 74ALVC374PW,112 specifies 300 MHz maximum clock frequency, while the Texas Instruments substitutes specify 150 MHz. Both values exceed typical application requirements for 8-bit parallel data storage. The lower specification on the substitute parts represents a conservative design margin and does not restrict their use in circuits designed for the original component.

Q: Are the 20-TSSOP packages physically identical?

A: Yes. All three parts use the 20-TSSOP package with identical physical dimensions (0.173" width, 4.40mm). PCB footprints and land patterns are directly compatible without modification.

Q: What is the difference between input capacitance values (4.6 pF vs. 5 pF)?

A: The substitute parts specify slightly higher input capacitance (5 pF vs. 4.6 pF). This minor difference does not affect functional compatibility and remains within acceptable design tolerances for standard logic circuit applications.

Q: Are compliance certifications maintained with the substitute parts?

A: Yes. Both SN74ALVCH374PW and SN74ALVCH374PWR maintain ROHS3 compliance and REACH unaffected status, matching the original component's regulatory profile.

Q: Why is the original 74ALVC374PW,112 classified as obsolete?

A: Obsolescence reflects Nexperia's product lifecycle management. The Texas Instruments equivalents (74ALVCH series) remain in active production, providing continuity for applications requiring this functional class of 8-bit D-type flip-flop logic.
