Substitute Part Grouping Explanation

Substitution of the 74ACT16823DL is determined by strict equivalence across the following critical parameters:

  • Functional Architecture: Dual 9-bit D-type flip-flop with master reset capability
  • Output Configuration: Tri-state, non-inverted outputs
  • Electrical Performance: 90 MHz clock frequency, 11.5 ns maximum propagation delay at 5V and 50pF load
  • Voltage Specifications: 4.5V to 5.5V supply voltage range
  • Output Drive Capability: 24 mA source and sink current
  • Package Compatibility: 56-BSSOP surface mount package with identical pinout and mechanical dimensions
  • Environmental Compliance: ROHS3 compliance, MSL Level 1, REACH unaffected status

The substitute part must match all electrical characteristics, functional specifications, and package requirements without deviation. Packaging format (Tube versus Tape & Reel) does not affect electrical or functional equivalence.

Engineering Selection Recommendations

The 74ACT16823DLR is the direct equivalent substitute for the 74ACT16823DL. Both parts are manufactured by Texas Instruments and share identical electrical specifications, functional architecture, and package configuration. The primary distinction is product status: the main part (74ACT16823DL) is designated Last Time Buy, while the substitute (74ACT16823DLR) maintains Active status.

The 74ACT16823DLR is available in Tape & Reel packaging format, which is standard for high-volume production environments and provides superior handling characteristics compared to tube packaging. Both parts maintain full ROHS3 compliance and carry identical environmental certifications (REACH unaffected, MSL Level 1).

For new designs or long-term production requirements, the 74ACT16823DLR is the appropriate selection due to its active product status and assured long-term availability. For existing designs currently using the 74ACT16823DL, direct substitution with the 74ACT16823DLR requires no circuit modifications, PCB layout changes, or firmware adjustments.

Frequently Asked Questions (FAQ)

Q: Can the 74ACT16823DLR be used as a direct replacement for the 74ACT16823DL in existing designs?

A: Yes. Both parts are electrically and functionally identical with matching pinouts and package dimensions. No circuit modifications are required for substitution.

Q: What is the difference between the tube and tape & reel packaging formats?

A: Tube packaging (74ACT16823DL) is suitable for manual handling and small-quantity applications. Tape & Reel packaging (74ACT16823DLR) is designed for automated pick-and-place assembly and high-volume production. The electrical and functional specifications are identical.

Q: Why is the 74ACT16823DL designated as Last Time Buy?

A: Last Time Buy status indicates that the manufacturer will discontinue production of this part number. Existing inventory will be sold until depletion, after which the part will no longer be available. The 74ACT16823DLR remains in active production.

Q: Are there any differences in compliance certifications between these parts?

A: No. Both the 74ACT16823DL and 74ACT16823DLR carry identical ROHS3 compliance, REACH unaffected status, and MSL Level 1 moisture sensitivity ratings.

Q: What is the recommended lead time for the 74ACT16823DLR?

A: Lead time information is not provided in the technical specifications. Contact the supplier or manufacturer for current availability and delivery schedules.

Q: Can these parts be used interchangeably in high-speed digital applications?

A: Yes. Both parts support 90 MHz clock frequency operation with 11.5 ns maximum propagation delay at 5V and 50pF load, meeting the timing requirements of standard high-speed digital logic applications.
