Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74ACT11373DW is determined by strict equivalence across the following critical parameters:

• Logic Function: D-Type Transparent Latch with identical 8:8 circuit configuration
• Electrical Performance: Matching supply voltage range (4.5V ~ 5.5V), propagation delay (8.5ns), and output current specifications (24mA high and low)
• Package Compatibility: Identical 24-SOIC surface mount package with matching physical dimensions
• Environmental & Compliance: Operating temperature range (-40°C ~ 85°C), RoHS3 compliance, and MSL rating (1)

The primary distinction between the main part and its substitute relates to packaging format and product lifecycle status. The 74ACT11373DWR maintains identical electrical and functional specifications while differing only in distribution packaging (Tape & Reel versus Tube) and current availability status (Active versus Last Time Buy).

Parameter Comparison

Engineering Selection Recommendations

The 74ACT11373DWR is the direct functional equivalent of the 74ACT11373DW. Both parts are manufactured by Texas Instruments and maintain identical electrical specifications, logic function, and package configuration. The 74ACT11373DWR is recommended for new designs and ongoing production due to its Active product status, ensuring continued availability and supply chain stability. The 74ACT11373DW, classified as Last Time Buy, is suitable only for legacy system maintenance or existing inventory replenishment where supply permits.

Both parts satisfy ROHS3 compliance requirements and carry MSL rating 1, indicating no moisture sensitivity constraints during standard handling and storage. Selection between these parts should be based on procurement requirements: Tube packaging (74ACT11373DW) for lower-volume applications or Tape & Reel packaging (74ACT11373DWR) for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 74ACT11373DWR be used as a direct replacement for the 74ACT11373DW in existing designs?

A: Yes. Both parts are electrically and functionally identical. The only differences are packaging format (Tube versus Tape & Reel) and product lifecycle status. PCB layout, schematic integration, and electrical performance remain unchanged.

Q: What is the significance of the Last Time Buy status on the 74ACT11373DW?

A: Last Time Buy indicates that Texas Instruments has discontinued production of this part number. Existing inventory may be available through authorized distributors, but long-term availability is not guaranteed. The 74ACT11373DWR, with Active status, represents the recommended path for sustained supply.

Q: Are there any electrical performance differences between Tube and Tape & Reel packaging?

A: No. Packaging format affects only distribution method and handling procedures. Electrical specifications, performance characteristics, and reliability remain identical regardless of packaging type.

Q: What are the key parameters that define substitution eligibility for this logic IC?

A: Substitution is determined by matching: logic function (D-Type Transparent Latch 8:8), supply voltage range (4.5V ~ 5.5V), propagation delay (8.5ns), output current (24mA), operating temperature range (-40°C ~ 85°C), and package type (24-SOIC surface mount). All these parameters must align for functional equivalence.

Q: Is the 74ACT11373DWR suitable for high-volume production?

A: Yes. The Tape & Reel packaging format of the 74ACT11373DWR is optimized for automated pick-and-place assembly processes, making it the preferred choice for high-volume manufacturing. Active product status ensures reliable supply chain support.
