Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74ACT11244DW is determined by strict equivalence across the following critical parameters:

• Logic Type: Buffer, Non-Inverting
• Number of Elements: 2
• Number of Bits per Element: 4
• Output Type: 3-State
• Current - Output High, Low: 24mA, 24mA
• Voltage - Supply: 4.5V ~ 5.5V
• Operating Temperature: -40°C ~ 85°C (TA)
• Package / Case: 24-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount

The 74ACT11244DWR meets all substitution criteria as a direct equivalent, differing only in packaging format (Cut Tape & Digi-Reel versus Tube) and product status (Active versus Last Time Buy).

Parameter Comparison

Engineering Selection Recommendations

The 74ACT11244DWR is the direct substitute for the 74ACT11244DW. Both parts are manufactured by Texas Instruments and maintain identical electrical and mechanical specifications. The primary distinction is product status: the 74ACT11244DW is Last Time Buy, while the 74ACT11244DWR is Active. For new designs or ongoing production requiring this buffer IC, the 74ACT11244DWR is the appropriate selection due to its active status and continued availability. Both parts satisfy ROHS3 compliance and REACH requirements, ensuring regulatory alignment for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the 74ACT11244DWR directly replace the 74ACT11244DW in existing designs?

A: Yes. Both parts are electrically and mechanically identical, with matching pin configurations, electrical characteristics, and package dimensions. The substitution is direct with no circuit modifications required.

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

A: Tube packaging contains components in a plastic tube for manual handling and small-quantity applications. Cut Tape & Digi-Reel packaging provides components on continuous tape for automated pick-and-place assembly. The internal component specifications remain identical.

Q: Why is the 74ACT11244DW marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this specific part number. The 74ACT11244DWR remains in active production and serves as the recommended alternative for continued supply.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts deliver identical electrical performance: 24mA output current capability, 4.5V to 5.5V supply voltage operation, and -40°C to 85°C operating temperature range.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 74ACT11244DW and 74ACT11244DWR are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (Unlimited) moisture sensitivity classification.
