SN74ACT04NSRG4 Equivalent & Substitute Parts

Part Overview

The SN74ACT04NSRG4 is a 6-channel inverter logic IC manufactured by Texas Instruments in a 14-SO surface mount package. This part is discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing production and maintenance applications. The 74ACT04 series provides standard inverter functionality suitable for digital logic circuits requiring signal inversion across multiple channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74ACT04NSRG4 is determined by strict equivalence across the following critical parameters:

• Logic Type: Inverter (6-channel, 1 input per channel)
• Voltage Supply Range: 4.5V ~ 5.5V
• Current Output Capability: 24mA high and low
• Input Logic Levels: 0.8V low, 2V high
• Propagation Delay: 8.5ns @ 5V, 50pF
• Operating Temperature Range: -40°C ~ 85°C
• Mounting Type: Surface Mount
• Base Product Number: 74ACT04 series
• Compliance: ROHS3, REACH Unaffected, EAR99

All substitute parts listed maintain these electrical and mechanical specifications. Packaging format differences (Tape & Reel, Tube, Cut Tape) do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain functional equivalence to the SN74ACT04NSRG4 across critical electrical parameters. Selection should be based on the following factors:

Product Status: The SN74ACT04NSRG4 is discontinued at DiGi Electronics. All substitute parts listed carry Active product status, ensuring long-term availability and supply chain continuity.

Manufacturer Equivalence: SN74ACT04NSR from Texas Instruments provides direct manufacturer continuity with identical quiescent current specifications (2 µA) and package dimensions (0.209", 5.30mm width). This part is the closest functional equivalent.

Cross-Manufacturer Alternatives: onsemi parts (MC74ACT04DR2G, 74ACT04SC, 74ACT04SCX) maintain all critical electrical specifications with slightly elevated quiescent current (4 µA maximum). Package width differs (0.154", 3.90mm), which may require PCB layout verification for existing designs.

Compliance and Certifications: All substitute parts are ROHS3 compliant, REACH unaffected, and classified as EAR99. Moisture sensitivity level remains 1 (Unlimited) across all options.

Packaging Considerations: Packaging format (Tape & Reel, Tube, Cut Tape) does not affect functional performance. Selection should align with procurement and assembly requirements. The 74ACT04SCX variant offers the highest inventory availability (110558 Pcs).

Frequently Asked Questions (FAQ)

Q: Can I use SN74ACT04NSR as a direct replacement for SN74ACT04NSRG4?

A: Yes. SN74ACT04NSR is functionally equivalent with identical electrical specifications and package dimensions. The primary difference is packaging format (Tape & Reel versus the original format). Both are Texas Instruments products with the same quiescent current rating (2 µA).

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

A: All parts maintain identical logic function, voltage supply range, output current capability, and propagation delay. The onsemi variants (MC74ACT04DR2G, 74ACT04SC, 74ACT04SCX) have a maximum quiescent current of 4 µA compared to 2 µA for Texas Instruments parts. Package case width also differs (0.154" versus 0.209"), requiring verification against PCB layout constraints.

Q: Are there any compatibility issues with different package widths?

A: The 14-SOIC package is standardized across all parts. The width difference (0.209" for Texas Instruments, 0.154" for onsemi) reflects different manufacturing specifications within the 14-SOIC standard. Verify PCB footprint compatibility before selection, particularly for high-density layouts.

Q: Which substitute part should I choose for new production?

A: Selection depends on design constraints and supply requirements. For maximum compatibility with existing designs, use SN74ACT04NSR (Texas Instruments, same package width). For highest inventory availability, use 74ACT04SCX (onsemi, 110558 Pcs in stock). All parts meet identical functional and compliance requirements.

Q: Do all substitute parts have the same operating temperature range?

A: Yes. All substitute parts operate across -40°C to 85°C, matching the original SN74ACT04NSRG4 specification.

Q: Are there RoHS and REACH compliance differences between substitutes?

A: No. All substitute parts are ROHS3 compliant and REACH unaffected, identical to the original part.
