Substitute Part Grouping Explanation

Substitution eligibility for the 74ACT11374DW is determined by strict equivalence across the following critical parameters:

• Functional Architecture: D-Type flip-flop with 1 element, 8-bit configuration
• Output Characteristics: Tri-state, non-inverted output configuration
• Electrical Performance: 70 MHz clock frequency, 11.3 ns maximum propagation delay at 5V and 50pF load
• Trigger Mechanism: Positive edge triggering
• Supply Voltage Range: 4.5V to 5.5V operation
• Output Drive Capability: 24 mA source and sink current
• Package Specification: 24-SOIC surface mount package with 0.295" (7.50mm) width
• Environmental Compliance: ROHS3 compliance, MSL Level 1, REACH unaffected status

Substitute parts must maintain identical electrical specifications and package dimensions to ensure direct replacement without circuit redesign or board layout modification.

Parameter Comparison

Engineering Selection Recommendations

The 74ACT11374DWR serves as the direct functional equivalent to the 74ACT11374DW. Both components are manufactured by Texas Instruments and share identical electrical specifications, performance characteristics, and package dimensions. The primary distinction between these parts is product status and packaging format.

The 74ACT11374DW is designated Last Time Buy, indicating end-of-life status with no further production planned. The 74ACT11374DWR maintains Active product status, ensuring continued availability and supply chain support. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and regulatory requirements.

The packaging difference—Tube format for the main part versus Tape & Reel format for the substitute—reflects standard distribution practices. Tape & Reel packaging is the industry standard for high-volume surface mount assembly operations and provides superior handling characteristics for automated pick-and-place equipment.

Selection of the 74ACT11374DWR is appropriate for new designs and production continuity, as it provides identical electrical performance with the advantage of active product status and standard supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the 74ACT11374DWR directly replace the 74ACT11374DW in existing designs?

A: Yes. Both components are electrically and mechanically identical. The 74ACT11374DWR operates across the same voltage range (4.5V to 5.5V), delivers identical propagation delay (11.3 ns at 5V, 50pF), and is packaged in the same 24-SOIC form factor. No circuit modifications or board layout changes are required.

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

A: Tube packaging contains loose components in a plastic tube, suitable for manual assembly or small-quantity handling. Tape & Reel packaging places components on a continuous carrier tape wound on a reel, optimized for automated surface mount assembly. Both formats contain identical components with identical electrical specifications.

Q: Why is the 74ACT11374DW marked as Last Time Buy?

A: Last Time Buy designation indicates that Texas Instruments has discontinued production of this specific part number. The 74ACT11374DWR, with identical specifications and Active product status, is the recommended alternative for ongoing supply and future production requirements.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the 74ACT11374DW and 74ACT11374DWR maintain ROHS3 compliance, MSL Level 1 rating, and REACH unaffected status. Environmental and regulatory compliance is identical across both part numbers.

Q: What is the significance of the "R" suffix in 74ACT11374DWR?

A: The "R" suffix indicates Tape & Reel packaging format, the standard distribution method for surface mount components in production environments. The electrical specifications and performance characteristics remain unchanged from the base part number.
