SN74ACT00DRG4 Equivalent & Substitute Parts

Part Overview

The SN74ACT00DRG4 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, identifying equivalent and substitute parts from active manufacturers ensures design continuity and supply chain reliability for applications requiring 4-channel 2-input NAND gate functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SN74ACT00DRG4 is determined by strict equivalence across the following critical parameters:

• Logic Type: NAND Gate
• Number of Circuits: 4
• Number of Inputs: 2 per circuit
• 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 @ V, Max CL: 9ns @ 5V, 50pF
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts are grouped into two categories: Parametric Equivalents and Manufacturer Recommended alternatives. Parametric Equivalents maintain identical electrical and mechanical specifications. Manufacturer Recommended alternatives are sourced from onsemi and feature extended operating temperature ranges (-55°C ~ 125°C) and slightly elevated quiescent current (4 µA maximum), while maintaining all other critical parameters.

Parameter Comparison

Engineering Selection Recommendations

SN74ACT00DR (Texas Instruments) is the primary parametric equivalent. This part maintains identical electrical specifications and operating temperature range to the SN74ACT00DRG4 while offering active product status and significantly higher inventory availability (59,099 units). The only difference is packaging format (Cut Tape & Digi-Reel versus the original specification), which does not affect electrical performance or PCB compatibility.

MC74ACT00DG and MC74ACT00DR2G (onsemi) are manufacturer-recommended alternatives suitable for applications requiring extended operating temperature ranges (-55°C ~ 125°C). These parts exhibit slightly elevated quiescent current (4 µA maximum versus 2 µA), which may impact low-power applications. Both maintain full electrical equivalence across all other parameters and ROHS3 compliance. MC74ACT00DG is supplied in Tube packaging, while MC74ACT00DR2G is supplied in Tape & Reel format.

74ACT00SCX (Fairchild Semiconductor) is a parametric equivalent with identical specifications to the SN74ACT00DRG4, including quiescent current and operating temperature range. This part offers the highest inventory availability (40,816 units) among all substitutes and maintains full ROHS3 compliance.

For applications with standard operating temperature requirements (-40°C ~ 85°C), SN74ACT00DR or 74ACT00SCX are preferred due to lower quiescent current specifications. For extended temperature applications, MC74ACT00DG or MC74ACT00DR2G provide the necessary thermal performance.

Frequently Asked Questions (FAQ)

Q: Can SN74ACT00DR be used as a direct replacement for SN74ACT00DRG4?

A: Yes. SN74ACT00DR is a parametric equivalent with identical electrical specifications, logic configuration, and package dimensions. The only difference is packaging format (Cut Tape & Digi-Reel versus the original specification), which does not affect circuit performance or PCB assembly compatibility.

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

A: MC74ACT00DG and MC74ACT00DR2G feature extended operating temperature ranges (-55°C ~ 125°C) compared to the standard -40°C ~ 85°C range. Quiescent current is specified at 4 µA maximum versus 2 µA for the original part. All other electrical parameters remain identical. These parts are suitable for applications requiring wider temperature operation.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited), matching the original SN74ACT00DRG4 specifications.

Q: Does the 14-SOIC package remain consistent across all substitutes?

A: Yes. All substitute parts use the 14-SOIC (0.154", 3.90mm Width) package, ensuring mechanical and electrical compatibility with existing PCB designs without layout modifications.

Q: Which substitute offers the best supply availability?

A: 74ACT00SCX from Fairchild Semiconductor offers the highest inventory availability at 40,816 units, followed by SN74ACT00DR at 59,099 units. Both are parametric equivalents with identical specifications to the original part.

Q: Can onsemi parts be used in applications with standard temperature requirements?

A: Yes. MC74ACT00DG and MC74ACT00DR2G function correctly within standard operating temperature ranges (-40°C ~ 85°C). The extended temperature capability (-55°C ~ 125°C) provides additional margin but is not required for standard applications. The slightly elevated quiescent current (4 µA) should be evaluated for power-sensitive designs.
