Substitute Part Grouping Explanation

Substitute parts for the SN74ACT11DG4 are qualified based on the following criteria:

• Logic Function: All substitutes must implement 3-channel, 3-input AND gate logic
• Electrical Specifications: Supply voltage range (4.5V ~ 5.5V), input logic levels (Low: 0.8V, High: 2V), output current (24mA, 24mA), and propagation delay (9.5ns @ 5V, 50pF) must be identical or equivalent
• Package Compatibility: All substitutes must use the 14-SOIC package form factor
• Compliance: RoHS3 compliance and MSL Level 1 rating required
• Base Product Number: All parts belong to the 74ACT11 family

The following parts meet these substitution criteria:

1. SN74ACT11DR (Texas Instruments) - Active status, Tape & Reel packaging
2. SN74ACT11D (Texas Instruments) - Last Time Buy status, Tube packaging
3. MC74ACT11DR2G (onsemi) - Active status, Tape & Reel packaging

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: SN74ACT11DR

The SN74ACT11DR is the preferred substitute for the SN74ACT11DG4. Both parts are manufactured by Texas Instruments and share identical electrical specifications. The SN74ACT11DR carries Active product status, ensuring long-term availability and supply continuity. The primary difference is packaging format: SN74ACT11DR is supplied in Tape & Reel format, which is standard for high-volume production environments. Both parts maintain ROHS3 compliance and MSL Level 1 rating.

Secondary Recommendation: MC74ACT11DR2G

The MC74ACT11DR2G, manufactured by onsemi, provides an alternative from a different supplier. This part meets all electrical and mechanical substitution criteria with one exception: quiescent current is specified at 4 µA maximum, compared to 2 µA for the Texas Instruments variants. This difference is within acceptable tolerance for most applications. The MC74ACT11DR2G carries Active product status and is supplied in Tape & Reel format. Selection of this part provides supply chain diversification.

Tertiary Option: SN74ACT11D

The SN74ACT11D is a Texas Instruments part with identical electrical specifications to the SN74ACT11DG4. However, this part carries Last Time Buy status, indicating limited future availability. Use of this part should be limited to applications requiring immediate procurement or as a temporary solution pending transition to an Active status part.

Frequently Asked Questions (FAQ)

Q: Can SN74ACT11DR be used as a direct replacement for SN74ACT11DG4?

A: Yes. Both parts are electrically and mechanically equivalent. The primary difference is packaging format: SN74ACT11DR uses Tape & Reel packaging while SN74ACT11DG4 uses Tube packaging. Both are 14-SOIC surface mount packages with identical pin configurations and electrical performance.

Q: What is the significance of the packaging difference between Tube and Tape & Reel?

A: Tube packaging is typically used for lower-volume orders and manual assembly processes. Tape & Reel packaging is standard for automated pick-and-place assembly and high-volume production. The choice depends on manufacturing process requirements, not electrical compatibility.

Q: Is MC74ACT11DR2G fully compatible with SN74ACT11DG4?

A: MC74ACT11DR2G is functionally and mechanically compatible. The quiescent current specification differs (4 µA maximum versus 2 µA), which may impact power consumption calculations in low-power applications. Verify power budget requirements before selection.

Q: Why is SN74ACT11DG4 marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued or will discontinue production. Customers requiring this part number should transition to an Active status equivalent such as SN74ACT11DR or MC74ACT11DR2G to ensure long-term supply availability.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitutes maintain ROHS3 compliance and MSL Level 1 rating, meeting environmental and reliability standards equivalent to the original part.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the design accommodates the packaging format change. Pin configurations, electrical specifications, and operating characteristics are identical across all qualified substitutes. No circuit modifications are required.
