Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74ACT04DG4 is determined by strict equivalence across the following parameters:

• Logic Type: Inverter
• Number of Circuits: 6
• Number of Inputs: 1
• Package / Case: 14-SOIC (0.154", 3.90mm Width)
• Voltage - Supply: 4.5V ~ 5.5V
• Current - Output High, Low: 24mA, 24mA
• Input Logic Level - Low: 0.8V
• Input Logic Level - High: 2V
• Max Propagation Delay @ 5V, 50pF: 8.5ns
• Operating Temperature: -40°C ~ 85°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All substitute parts listed maintain these electrical and mechanical specifications. Variations in Current - Quiescent (Max) and packaging format (Cut Tape, Tube, Tape & Reel) do not affect functional substitution.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: SN74ACT04DR

The SN74ACT04DR is the direct active equivalent from Texas Instruments. It maintains identical electrical specifications to the SN74ACT04DG4, including Current - Quiescent (Max) of 2 µA, and is currently in active production status. This part is available in Cut Tape and Digi-Reel packaging formats.

Secondary Recommendations: 74ACT04SCX and MC74ACT04DR2G

Both 74ACT04SCX (onsemi, Cut Tape & Digi-Reel) and MC74ACT04DR2G (onsemi, Tape & Reel) are active alternatives from onsemi. These parts maintain all critical electrical parameters and are ROHS3 compliant. The Current - Quiescent (Max) specification is 4 µA, which remains within acceptable operating margins for standard inverter applications.

Alternative: 74ACT04SC

The 74ACT04SC from onsemi is available in Tube packaging and maintains full electrical equivalence with a Current - Quiescent (Max) of 4 µA. This option is suitable for applications where tube packaging is preferred.

Discontinued Parts: SN74ACT04D

The SN74ACT04D is discontinued at DiGi Electronics but remains functionally equivalent. This part should be considered only if existing inventory is available and active alternatives are unavailable.

All substitute parts are ROHS3 compliant and carry MSL rating of 1 (Unlimited), matching the compliance profile of the original part.

Frequently Asked Questions (FAQ)

Q: Can I directly replace SN74ACT04DG4 with SN74ACT04DR?

A: Yes. The SN74ACT04DR is the direct active equivalent from Texas Instruments. Both parts maintain identical electrical specifications, operate across the same voltage and temperature ranges, and use the same 14-SOIC package. The primary difference is packaging format and product status (active vs. discontinued).

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

A: Both manufacturers produce 74ACT04 series inverters that meet the same electrical specifications. The primary differences are Current - Quiescent (Max) specifications (2 µA for Texas Instruments vs. 4 µA for onsemi) and packaging availability. All versions maintain identical logic performance, propagation delay, and output drive capability.

Q: Does packaging format affect substitution?

A: Packaging format (Cut Tape, Tube, Tape & Reel) does not affect electrical substitution. The choice depends on your procurement and assembly requirements. All listed parts use the same 14-SOIC physical package and are surface mount compatible.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance and MSL rating of 1 (Unlimited), matching the compliance requirements of the original SN74ACT04DG4.

Q: What does Current - Quiescent (Max) variation mean for my application?

A: Current - Quiescent (Max) represents the maximum supply current when no outputs are switching. The variation between 2 µA (Texas Instruments) and 4 µA (onsemi) is negligible for standard logic applications and does not affect functional performance or output specifications.

Q: Can I use 74ACT04SCX in high-volume production?

A: Yes. The 74ACT04SCX is in active production status with substantial inventory (110,558 Pcs) and is available in Cut Tape & Digi-Reel packaging, making it suitable for automated assembly and high-volume applications.
