Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74ACT16825DL is determined by strict equivalence across the following critical parameters:

• Logic function: Non-inverting buffer with identical element and bit configuration (2 elements, 9 bits per element)
• Output architecture: 3-state output capability
• Electrical specifications: 24mA output current (high and low), 4.5V to 5.5V supply voltage range
• Temperature range: -40°C to 85°C operating specification
• Package format: 56-BSSOP surface mount package with identical physical dimensions
• Compliance standards: ROHS3 compliance and MSL Level 1 rating

The 74ACT16825DLR qualifies as a direct substitute based on identical electrical and mechanical parameters. The primary distinction is packaging format: the main part uses Tube packaging while the substitute uses Tape & Reel (TR) format. Both parts share the same base product number (74ACT16825) and are manufactured by Texas Instruments.

Parameter Comparison

Engineering Selection Recommendations

The 74ACT16825DLR is a direct functional and electrical equivalent to the 74ACT16825DL. Both parts maintain identical logic specifications, electrical performance, and physical package dimensions. The 74ACT16825DLR is preferred for new designs due to its Active product status, whereas the main part is designated Last Time Buy.

The packaging format difference (Tube versus Tape & Reel) does not affect electrical performance or PCB assembly compatibility. Selection between these parts should be based on procurement requirements and production volume considerations. The 74ACT16825DLR's Active status ensures long-term availability and supply chain continuity.

Both parts satisfy ROHS3 compliance and REACH requirements, making them suitable for applications with environmental and regulatory compliance mandates.

Frequently Asked Questions (FAQ)

Q: Can the 74ACT16825DLR directly replace the 74ACT16825DL in existing designs?

A: Yes. The 74ACT16825DLR is electrically and functionally identical to the 74ACT16825DL. Both parts feature the same logic configuration, output specifications, supply voltage range, and operating temperature range. No circuit modifications are required.

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

A: Tube packaging supplies components in plastic tubes for manual handling and small-quantity applications. Tape & Reel (TR) packaging supplies components on continuous tape for automated pick-and-place assembly equipment. Both formats contain identical components with no electrical differences.

Q: Why is the 74ACT16825DL marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this part number. The 74ACT16825DLR, with Active status, represents the current production equivalent and is recommended for all new designs.

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

A: No. Both the 74ACT16825DL and 74ACT16825DLR maintain identical ROHS3 compliance, REACH status, and Moisture Sensitivity Level (MSL) ratings. Both parts are suitable for applications requiring environmental and regulatory compliance.

Q: What are the critical parameters for substitution compatibility?

A: Substitution compatibility is determined by: logic type (non-inverting buffer), element count (2), bit configuration (9 bits per element), output type (3-state), output current (24mA), supply voltage range (4.5V to 5.5V), operating temperature (-40°C to 85°C), and package format (56-BSSOP surface mount). All these parameters are identical between the main part and substitute.
