Substitute Part Grouping Explanation

Substitution eligibility for the 74ACT16244DGG is determined by strict equivalence across the following critical parameters:

• Logic Type: Buffer, Non-Inverting configuration
• Element and Bit Configuration: 4 elements with 4 bits per element
• Output Architecture: 3-State output capability
• Current Specifications: 24mA output drive for both high and low states
• Supply Voltage Range: 4.5V to 5.5V operation
• Temperature Range: -40°C to 85°C (TA)
• Physical Package: 48-TFSOP form factor with 0.240" width (6.10mm)
• Surface Mount Mounting Type
• Compliance Standards: ROHS3 Compliant, MSL Level 1

Substitute parts must maintain identical electrical performance and physical compatibility to ensure direct replacement without circuit redesign or PCB layout modification.

Parameter Comparison

Engineering Selection Recommendations

The 74ACT16244DGGR is the manufacturer-recommended substitute for the 74ACT16244DGG. Both components are manufactured by Texas Instruments and maintain identical electrical specifications and physical package dimensions.

The primary distinction between these parts is product status and packaging format. The 74ACT16244DGG operates under Last Time Buy status, indicating end-of-life production. The 74ACT16244DGGR maintains Active product status, ensuring continued availability and supply chain support from the manufacturer.

Packaging differs between the two parts: the 74ACT16244DGG is supplied in Tube format, while the 74ACT16244DGGR is supplied in Tape & Reel (TR) format. Both packaging formats are compatible with standard surface mount assembly processes. The Tape & Reel format of the 74ACT16244DGGR is typically preferred for high-volume production environments due to automated handling capabilities.

Both components maintain ROHS3 compliance and MSL Level 1 rating, confirming environmental and moisture handling equivalence. Selection between these parts should be based on supply availability, production volume requirements, and packaging format compatibility with existing assembly infrastructure.

Frequently Asked Questions (FAQ)

Q: Can the 74ACT16244DGGR directly replace the 74ACT16244DGG in existing designs?

A: Yes. The 74ACT16244DGGR is electrically and mechanically equivalent to the 74ACT16244DGG. Both components feature identical logic type, element configuration, output specifications, supply voltage range, operating temperature range, and 48-TFSOP package dimensions. Direct substitution requires no circuit redesign or PCB 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-volume applications. Tape & Reel packaging supplies components on continuous carrier tape wound on reels, optimized for automated pick-and-place assembly equipment used in high-volume production. Both formats contain identical components with equivalent electrical performance.

Q: Why is the 74ACT16244DGG marked as Last Time Buy?

A: Last Time Buy status indicates that the manufacturer has ceased or will cease production of this specific part number. Customers requiring this component must place final orders before production ends. The 74ACT16244DGGR, with Active product status, represents the ongoing production alternative.

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

A: No. Both the 74ACT16244DGG and 74ACT16244DGGR maintain identical ROHS3 compliance, MSL Level 1 rating, REACH Unaffected status, and ECCN/HTSUS classifications. Compliance and environmental certifications are equivalent.

Q: What output current specifications apply to both parts?

A: Both components provide 24mA output drive capability for high state and 24mA for low state operation. These specifications remain constant across the 4.5V to 5.5V supply voltage range and -40°C to 85°C operating temperature range.
