Engineering Selection Recommendations

SN74ACT11DR (Texas Instruments): This part is the direct equivalent to the SN74ACT11DRG4, differing only in packaging format (Tape & Reel versus tube). The SN74ACT11DR maintains identical electrical specifications and is currently in active production status with 3540 units in stock. This part is the primary substitute for applications requiring Texas Instruments sourcing or supply chain continuity.

MC74ACT11DR2G (onsemi): This part provides functional and electrical equivalence with a maximum quiescent current specification of 4µA compared to 2µA for the Texas Instruments variants. All other parameters, including propagation delay, output current capability, and operating temperature range, remain identical. The MC74ACT11DR2G is actively produced by onsemi with 3253 units in stock and is suitable for applications where multi-source qualification is required.

Both substitute parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the SN74ACT11DR be used as a direct replacement for the SN74ACT11DRG4?

A: Yes. The SN74ACT11DR is electrically and functionally equivalent. The primary difference is packaging format: the SN74ACT11DRG4 is supplied in tube packaging, while the SN74ACT11DR is supplied in Tape & Reel format. Both use the 14-SOIC package with identical pin configuration and electrical performance.

Q: What is the difference between the Texas Instruments and onsemi versions?

A: The MC74ACT11DR2G (onsemi) has a maximum quiescent current specification of 4µA, compared to 2µA for Texas Instruments parts. All other electrical parameters, including propagation delay, output current, logic levels, and operating temperature range, are identical. Both are ROHS3 compliant and suitable for equivalent circuit operation.

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

A: No compatibility concerns exist for the specified parameters. All three parts share identical logic function, package type (14-SOIC), pin configuration, supply voltage range (4.5V ~ 5.5V), output current capability (24mA), and operating temperature range (-40°C ~ 85°C). PCB layout and schematic integration remain unchanged.

Q: Why is the SN74ACT11DRG4 discontinued?

A: The SN74ACT11DRG4 is discontinued at DiGi Electronics. The SN74ACT11DR remains in active production and serves as the recommended substitute for ongoing applications.

Q: Can I use the MC74ACT11DR2G in a design originally specified for the SN74ACT11DRG4?

A: Yes. The MC74ACT11DR2G meets all functional and electrical requirements. The slightly higher quiescent current (4µA maximum versus 2µA) does not affect circuit operation within the specified parameters and is acceptable for standard logic applications.

Q: What packaging formats are available for these substitute parts?

A: The SN74ACT11DR and MC74ACT11DR2G are supplied in Tape & Reel (TR) format. Both use the 14-SOIC surface mount package with 0.154" width (3.90mm). Standard reel quantities and handling procedures apply.
