Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74ACT11244PW is determined by strict equivalence across the following critical parameters:

• Logic function: Buffer, Non-Inverting configuration
• Element and bit architecture: 2 elements, 4 bits per element
• Output configuration: 3-State output capability
• Electrical performance: 24mA output current (high and low)
• Supply voltage range: 4.5V ~ 5.5V
• Temperature operating range: -40°C ~ 85°C
• Physical form factor: 24-TSSOP surface mount package with identical dimensions
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

The 74ACT11244PWR qualifies as a direct substitute based on identical electrical specifications, functional architecture, and package geometry. The distinction between these parts lies exclusively in packaging format: tube versus tape & reel.

Parameter Comparison

Engineering Selection Recommendations

The 74ACT11244PWR is the manufacturer-recommended substitute for the 74ACT11244PW. Both parts maintain identical electrical characteristics, functional specifications, and physical package dimensions. The primary distinction is product status: the 74ACT11244PW is Last Time Buy, while the 74ACT11244PWR remains in Active production status.

Selection between these parts should be based on packaging requirements and supply chain considerations. The 74ACT11244PWR in Tape & Reel format is suitable for high-volume automated assembly operations. The 74ACT11244PW in Tube format may be appropriate for lower-volume or manual assembly processes, though availability is limited due to Last Time Buy status.

Both parts satisfy ROHS3 compliance and REACH requirements, ensuring regulatory alignment for current manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can the 74ACT11244PWR directly replace the 74ACT11244PW in existing designs?

A: Yes. The 74ACT11244PWR is electrically and functionally identical to the 74ACT11244PW. Both parts feature the same logic architecture, output current specifications, supply voltage range, operating temperature range, and 24-TSSOP package dimensions. Substitution requires no circuit modifications.

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

A: Tube packaging (74ACT11244PW) contains individual components in a protective tube, suitable for manual handling and lower-volume applications. Tape & Reel packaging (74ACT11244PWR) presents components on continuous tape wound on a reel, optimized for automated pick-and-place assembly equipment. Both formats contain identical components with identical specifications.

Q: Why is the 74ACT11244PW marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this part number. The 74ACT11244PWR in Tape & Reel format remains in active production as the current standard offering. For new designs or long-term projects, the 74ACT11244PWR is the recommended part number.

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

A: No. Both the 74ACT11244PW and 74ACT11244PWR carry identical ROHS3 compliance and REACH Unaffected status. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for both parts, indicating no special moisture handling requirements.

Q: What are the critical parameters that define substitution eligibility for this part?

A: Substitution eligibility is determined by: logic function (Buffer, Non-Inverting), element count (2), bits per element (4), output type (3-State), output current (24mA high and low), supply voltage range (4.5V ~ 5.5V), operating temperature range (-40°C ~ 85°C), and package form factor (24-TSSOP surface mount). Any deviation in these parameters disqualifies a part as a direct substitute.
