74ACT16373DL Equivalent & Substitute Parts

Part Overview

The 74ACT16373DL is a D-Type Transparent Latch logic IC featuring dual 8:8 channel configuration with tri-state output capability. This component operates within the 4.5V to 5.5V supply voltage range and is housed in a 48-SSOP surface mount package. The part is currently designated as Last Time Buy, indicating discontinued production status. Identifying equivalent substitute parts is essential for design continuity, inventory management, and long-term product support when original stock becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74ACT16373DL is determined by strict equivalence across the following critical parameters:

• Logic Function: D-Type Transparent Latch with identical 8:8 channel configuration and dual independent circuits
• Electrical Specifications: Matching supply voltage range (4.5V ~ 5.5V), propagation delay (9.3ns), and output current ratings (24mA high/low)
• Output Architecture: Tri-state output capability required for bus interface compatibility
• Thermal Performance: Operating temperature range of -40°C ~ 85°C
• Physical Form Factor: 48-SSOP surface mount package with 0.295" width (7.50mm)
• Compliance Standards: ROHS3 compliance and MSL Level 1 rating

The 74ACT16373DLR qualifies as a direct substitute based on identical electrical and functional specifications. The primary distinction is packaging format: the substitute is supplied in Cut Tape (CT) and Digi-Reel® tape and reel configuration rather than tube packaging, with active product status versus Last Time Buy status.

Parameter Comparison

Engineering Selection Recommendations

The 74ACT16373DLR is a functionally equivalent substitute for the 74ACT16373DL. Both parts maintain identical electrical performance, thermal specifications, and compliance certifications (ROHS3, MSL Level 1). The primary consideration for component selection is packaging and product lifecycle status.

The 74ACT16373DL is designated Last Time Buy, indicating production discontinuation. The 74ACT16373DLR maintains Active product status and is available in tape and reel packaging, which is standard for high-volume manufacturing operations. For new designs or production runs requiring long-term supply assurance, the 74ACT16373DLR is the appropriate selection. For existing inventory management or low-volume applications where tube packaging is preferred, the 74ACT16373DL remains viable until stock depletion.

Both parts satisfy identical PCB assembly requirements, reflow soldering profiles, and functional integration within 48-SSOP footprints. No circuit redesign or board layout modification is required when transitioning between these parts.

Frequently Asked Questions (FAQ)

Q: Are the 74ACT16373DL and 74ACT16373DLR pin-compatible?

A: Yes. Both parts use the 48-SSOP package with identical pin assignments, electrical characteristics, and functional behavior. Direct substitution on the PCB is possible without layout modification.

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

A: Tube packaging supplies components in plastic tubes suitable for manual handling and small-quantity applications. Tape and reel packaging uses standardized carrier tape for automated pick-and-place assembly equipment. The 74ACT16373DLR tape and reel format is standard for high-volume manufacturing. Both packaging formats contain identical die and electrical performance.

Q: Why is the 74ACT16373DL marked Last Time Buy?

A: Last Time Buy designation indicates Texas Instruments has discontinued production of this part number. Existing inventory is available for purchase, but no future production runs are planned. The 74ACT16373DLR remains in active production as the current equivalent offering.

Q: Can I use the 74ACT16373DLR in applications originally designed for the 74ACT16373DL?

A: Yes. The 74ACT16373DLR is electrically and functionally identical. All electrical specifications, timing parameters, and thermal ratings are equivalent. Substitution is direct with no circuit modifications required.

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

A: No. Both parts carry identical ROHS3 compliance status and Moisture Sensitivity Level 1 rating. Environmental and regulatory certifications are equivalent.

Q: What is the minimum order quantity difference between packaging formats?

A: Tube packaging typically accommodates smaller order quantities suitable for prototyping and low-volume production. Tape and reel packaging is optimized for automated assembly and is often available in larger standard quantities. Consult supplier inventory for specific availability and minimum order requirements.
