SN74ACT11D Equivalent & Substitute Parts

Part Overview

The SN74ACT11D is a 3-channel AND gate logic IC manufactured by Texas Instruments in a 14-SOIC surface mount package. This part is designated as Last Time Buy, indicating end-of-life status. The SN74ACT11D operates within the 4.5V to 5.5V supply voltage range and is suitable for digital logic applications requiring AND gate functionality with three independent circuits, each with three inputs.

Due to the Last Time Buy status of the SN74ACT11D, identifying equivalent substitute parts with active product status ensures continued design support and supply chain reliability for new production runs and long-term availability.

Engineering Selection Recommendations

Both SN74ACT11DR and MC74ACT11DR2G are qualified substitutes for the SN74ACT11D based on electrical and mechanical parameter equivalence. The primary distinction is product status and manufacturer:

SN74ACT11DR is the direct Texas Instruments equivalent with Active product status, maintaining identical quiescent current specifications (2 µA) and packaging format (Tape & Reel). This part is recommended for designs requiring continuity with the original manufacturer's product line.

MC74ACT11DR2G is the onsemi equivalent with Active product status. The quiescent current specification is 4 µA, which remains within acceptable operational parameters for most applications. This part provides an alternative source from a qualified manufacturer within the 74ACT logic family.

Both substitutes maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with modern manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can SN74ACT11DR be used as a direct replacement for SN74ACT11D?

A: Yes. SN74ACT11DR is electrically and mechanically equivalent to SN74ACT11D. Both parts share identical logic specifications, supply voltage range, output drive capability, propagation delay, and operating temperature range. The primary difference is product status (Active vs. Last Time Buy) and packaging format (Tape & Reel vs. Tube).

Q: What is the difference between SN74ACT11DR and MC74ACT11DR2G?

A: Both parts are functionally equivalent AND gate ICs with identical circuit count, input configuration, and timing specifications. The key difference is quiescent current: SN74ACT11DR draws 2 µA maximum, while MC74ACT11DR2G draws 4 µA maximum. Both values are within acceptable operating parameters for 74ACT logic applications. The parts differ by manufacturer (Texas Instruments vs. onsemi).

Q: Are the package dimensions identical between all three parts?

A: Yes. All three parts use the 14-SOIC package with dimensions of 0.154" width and 3.90mm width. PCB layout and footprint compatibility is maintained across all substitutes.

Q: Does the packaging format (Tube vs. Tape & Reel) affect electrical performance?

A: No. Packaging format affects only handling, storage, and automated assembly compatibility. Electrical and functional performance is identical regardless of packaging format.

Q: Are all three parts RoHS compliant?

A: Yes. SN74ACT11D, SN74ACT11DR, and MC74ACT11DR2G are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
