MC74ACT11DR2G Equivalent & Substitute Parts

Part Overview

The MC74ACT11DR2G is a 3-channel AND gate logic IC manufactured by onsemi, housed in a 14-SOIC surface mount package. This component is actively produced and widely used in digital logic applications requiring multiple independent AND gate functions. The part is ROHS3 compliant with unlimited moisture sensitivity rating.

Substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required, or when sourcing from different manufacturers is preferred for supply chain optimization.

Substitute Part Grouping Explanation

Substitution eligibility for the MC74ACT11DR2G is determined by the following critical parameters:

Logic configuration: 3-channel AND gate with 3 inputs per channel
Electrical specifications: 4.5V ~ 5.5V supply voltage, 24mA output drive capability, 9.5ns maximum propagation delay at 5V with 50pF load
Input logic thresholds: 0.8V low, 2V high
Operating temperature range: -40°C ~ 85°C
Package format: 14-SOIC surface mount
Compliance: ROHS3 compliant, MSL 1

The substitute parts SN74ACT11DR and SN74ACT11D from Texas Instruments meet all electrical and functional requirements. Differences exist only in packaging format (Tape & Reel versus Tube) and quiescent current specifications (2µA versus 4µA maximum), with the lower quiescent current in Texas Instruments parts representing an improvement in power efficiency.

Engineering Selection Recommendations

For active production applications, the SN74ACT11DR from Texas Instruments is the primary substitute, offering identical electrical performance with improved quiescent current characteristics and active product status. Both the MC74ACT11DR2G and SN74ACT11DR are available in Tape & Reel packaging suitable for automated assembly processes.

The SN74ACT11D represents an alternative when Tube packaging is acceptable for lower-volume applications. However, this part carries Last Time Buy status, indicating limited future availability. Selection should prioritize the SN74ACT11DR for new designs and ongoing production.

All three parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard PCB assembly and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can SN74ACT11DR be used as a direct replacement for MC74ACT11DR2G?

A: Yes. Both parts are functionally and electrically equivalent 3-channel AND gate ICs in 14-SOIC packages with identical logic specifications, supply voltage range, output drive capability, propagation delay, and operating temperature range. The primary difference is quiescent current (2µA versus 4µA maximum), which favors the Texas Instruments part.

Q: What is the difference between SN74ACT11DR and SN74ACT11D?

A: Both parts are electrically identical. The difference is packaging format: SN74ACT11DR is supplied in Tape & Reel (TR) format for automated assembly, while SN74ACT11D is supplied in Tube format for manual handling or lower-volume applications. SN74ACT11D carries Last Time Buy status.

Q: Are there packaging compatibility concerns when switching between these parts?

A: No. All three parts use the same 14-SOIC (0.154", 3.90mm Width) surface mount package. PCB footprints and assembly processes remain unchanged. The only consideration is the supply format: Tape & Reel versus Tube.

Q: Do these parts require different handling or storage procedures?

A: No. All parts share MSL 1 (Unlimited) moisture sensitivity rating, requiring no special moisture control during storage or handling.

Q: Which part should be selected for new designs?

A: The SN74ACT11DR is recommended for new designs due to active product status and improved quiescent current performance. The MC74ACT11DR2G remains suitable for existing designs. The SN74ACT11D should be avoided for new designs due to Last Time Buy status.
