SN74ACT00DRE4 Equivalent & Substitute Parts

Part Overview

The SN74ACT00DRE4 is a NAND Gate IC with 4 channels and 2 inputs per channel, packaged in a 14-SOIC surface mount configuration. Manufactured by Texas Instruments, this component operates within the 74ACT logic family and is classified as obsolete. Due to its obsolete status and limited inventory availability (905 pieces), identifying functionally equivalent active alternatives is essential for design continuity and procurement reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SN74ACT00DRE4 is determined by strict adherence to the following parameters:

• Logic Type: NAND Gate (4 channels, 2 inputs per channel)
• Package: 14-SOIC form factor with identical physical dimensions
• Voltage Supply Range: 4.5V ~ 5.5V
• Input/Output Logic Levels: 0.8V (low), 2V (high)
• Max Propagation Delay: 9ns @ 5V, 50pF
• Current Output Capability: 24mA (high and low)
• Mounting Type: Surface Mount
• RoHS3 Compliance

Substitute parts are grouped into two categories:

Parametric Equivalents maintain identical electrical specifications and operating temperature ranges as the original part.

Manufacturer Recommended Equivalents are functionally compatible but may feature extended operating temperature ranges or slightly different quiescent current specifications while maintaining all critical switching and logic parameters.

Parameter Comparison

Engineering Selection Recommendations

SN74ACT00DR (Texas Instruments) is the primary substitute for the obsolete SN74ACT00DRE4. This part maintains identical electrical specifications and operating temperature range while offering active product status and significantly higher inventory availability (59,099 pieces). The only difference is packaging format (Cut Tape & Digi-Reel versus the original's unspecified packaging), which does not affect functional compatibility. ROHS3 compliance and MSL rating are identical.

MC74ACT00DG and MC74ACT00DR2G (onsemi) are manufacturer-recommended alternatives with active status and substantial inventory. Both parts maintain all critical electrical parameters and package dimensions. The extended operating temperature range (-55°C ~ 125°C versus -40°C ~ 85°C) provides additional thermal margin. Quiescent current is slightly elevated at 4 µA maximum compared to 2 µA in the original specification. These parts are suitable for applications requiring broader temperature operation or when onsemi supply chain preference is established.

74ACT00SCX (Fairchild Semiconductor) is a parametric equivalent with identical electrical specifications and operating temperature range to the original part. Inventory availability is substantial (40,816 pieces). RoHS and MSL compliance status are not specified in the provided data.

All substitute parts maintain ROHS3 compliance and are suitable for direct pin-for-pin replacement in 14-SOIC surface mount applications where the SN74ACT00DRE4 was originally specified.

Frequently Asked Questions (FAQ)

Q: Can I use MC74ACT00DG or MC74ACT00DR2G as direct replacements for the SN74ACT00DRE4?

A: Yes. Both onsemi parts are functionally compatible. They maintain identical logic function, package form factor, voltage supply range, input/output logic levels, propagation delay, and output current capability. The extended operating temperature range (-55°C ~ 125°C) is a superset of the original specification (-40°C ~ 85°C), making these parts suitable for applications across the original temperature range and beyond.

Q: What is the difference between SN74ACT00DR and the original SN74ACT00DRE4?

A: The SN74ACT00DR is functionally and electrically identical to the SN74ACT00DRE4. Both are Texas Instruments products with the same logic specifications, operating temperature range, and electrical characteristics. The primary difference is product status: SN74ACT00DR is active with high inventory availability, while SN74ACT00DRE4 is obsolete with limited stock.

Q: Are there any differences in quiescent current between substitute options?

A: SN74ACT00DR and 74ACT00SCX maintain the 2 µA maximum quiescent current specification identical to the original part. MC74ACT00DG and MC74ACT00DR2G specify 4 µA maximum quiescent current. For power-sensitive applications, SN74ACT00DR or 74ACT00SCX are preferred. For general applications, the 2 µA difference is negligible.

Q: Can I mix different substitute parts in the same design?

A: Yes. All substitute parts are electrically compatible and maintain identical logic function, propagation delay, and output drive capability. Pin-for-pin compatibility is maintained across all options in the 14-SOIC package.

Q: What packaging formats are available for these substitutes?

A: SN74ACT00DR is available in Cut Tape (CT) and Digi-Reel format. MC74ACT00DG is supplied in Tube packaging. MC74ACT00DR2G is supplied in Tape & Reel (TR) format. 74ACT00SCX packaging format is not specified. Selection should be based on your assembly process requirements and procurement volume.

Q: Are all substitute parts RoHS3 compliant?

A: SN74ACT00DR, MC74ACT00DG, and MC74ACT00DR2G are confirmed ROHS3 compliant. RoHS compliance status for 74ACT00SCX is not specified in the provided data and should be verified with the supplier.
