CD74AC00MG4 Equivalent & Substitute Parts

Part Overview

The CD74AC00MG4 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 logic component operates across a supply voltage range of 1.5V to 5.5V with a maximum propagation delay of 7.3ns at 5V with 50pF load. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives that maintain electrical and mechanical compatibility for ongoing production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD74AC00MG4 is determined by the following criteria:

Mandatory Compatibility Parameters:

• Logic Type: NAND Gate (4 channels, 2 inputs)
• Package / Case: 14-SOIC form factor
• Mounting Type: Surface Mount
• Base Product Number: 74AC00 series

Electrical Parameter Tolerance: Substitute parts must operate within the specified voltage supply range and maintain compatible input/output logic levels and current ratings. Propagation delay variations are acceptable provided the part functions within the 74AC00 logic family specifications.

Compliance Requirements: Parts must maintain ROHS3 compliance status for new production applications. Obsolete or non-compliant parts are identified for legacy system support only.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: CD74AC00M96 The CD74AC00M96 from Texas Instruments is the direct functional equivalent to the CD74AC00MG4. It maintains identical electrical specifications including voltage supply range (1.5V ~ 5.5V), quiescent current (4 µA), and propagation delay (7.3ns). The part is currently active with ROHS3 compliance and available in high inventory (5234 Pcs). The only difference is packaging format (Tape & Reel versus the original configuration), which does not affect electrical performance.

Secondary Recommendations: MC74AC00DR2G and MC74AC00DG Both onsemi parts (MC74AC00DR2G and MC74AC00DG) are active alternatives with ROHS3 compliance. These parts operate within a slightly higher voltage supply range (2V ~ 6V) and exhibit marginally longer propagation delay (8ns versus 7.3ns). Both maintain the required 4-channel, 2-input NAND gate configuration and 14-SOIC package. MC74AC00DR2G is available in Tape & Reel format with substantial inventory (18745 Pcs), while MC74AC00DG is available in Tube format (1408 Pcs).

Alternative for Extended Temperature Range: 74AC00SCX The 74AC00SCX from onsemi is suitable for applications not requiring the full -55°C to 125°C operating range. This part operates from -40°C to 85°C and features lower quiescent current (2 µA). It is ROHS3 compliant and available in high inventory (15865 Pcs) in Cut Tape & Digi-Reel format.

Legacy Support: CD74AC00M The CD74AC00M from Harris Corporation is obsolete and RoHS non-compliant. This part is suitable only for legacy system repairs where original specifications must be maintained and RoHS compliance is not required.

Frequently Asked Questions (FAQ)

Q: Can MC74AC00DR2G replace CD74AC00MG4 in new production designs? A: Yes. MC74AC00DR2G is functionally compatible with identical logic configuration (4-channel NAND gate, 2 inputs) and 14-SOIC package. The voltage supply range (2V ~ 6V) encompasses the original specification (1.5V ~ 5.5V) for most applications. Propagation delay difference (8ns versus 7.3ns) is within acceptable tolerance for 74AC00 series logic. ROHS3 compliance is maintained.

Q: What is the difference between CD74AC00M96 and CD74AC00MG4? A: These parts are electrically identical. The difference is packaging format: CD74AC00M96 is supplied in Tape & Reel format while CD74AC00MG4 was supplied in standard packaging. Both maintain identical electrical specifications and ROHS3 compliance.

Q: Is 74AC00SCX suitable for applications requiring -55°C operation? A: No. The 74AC00SCX operates from -40°C to 85°C and is not suitable for applications requiring the full -55°C to 125°C temperature range of the original CD74AC00MG4. Use MC74AC00DR2G or MC74AC00DG for extended low-temperature operation.

Q: Why does MC74AC00DR2G have a higher propagation delay (8ns) than CD74AC00MG4 (7.3ns)? A: Propagation delay variation is inherent to different manufacturers' process technology. The 8ns specification for MC74AC00DR2G remains within acceptable 74AC00 series performance parameters and does not affect functional compatibility in standard logic applications.

Q: Can I use CD74AC00M for new production? A: No. CD74AC00M is obsolete and RoHS non-compliant. It is suitable only for legacy system repairs where original part specifications must be maintained and regulatory compliance is not required.

Q: What packaging formats are available for active substitutes? A: CD74AC00M96 is available in Tape & Reel format. MC74AC00DR2G is available in Tape & Reel format. 74AC00SCX is available in Cut Tape & Digi-Reel format. MC74AC00DG is available in Tube format. Select packaging based on production volume and assembly requirements.
