CD74AC00M NAND Gate IC Equivalent & Substitute Parts

Part Overview

The CD74AC00M is a 4-channel 2-input NAND gate logic IC manufactured by Texas Instruments in 14-SOIC surface mount packaging. This part is discontinued at DiGi Electronics but remains available through alternative sources. Finding equivalent substitute parts is necessary due to product discontinuation status, though functionally identical alternatives from both Texas Instruments and onsemi are available in active production with comparable electrical characteristics and identical package specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD74AC00M is determined by the following criteria:

• Identical logic function: 4-channel 2-input NAND gate
• Identical package: 14-SOIC surface mount
• Compatible voltage supply range: minimum 1.5V operation required
• Matching output drive capability: 24mA high and low
• Propagation delay within acceptable tolerance: 7.3ns to 8ns @ 5V, 50pF load
• Identical pin configuration and base product number: 74AC00

All listed substitute parts meet these criteria. Variations in operating temperature range and quiescent current do not affect functional substitution in standard applications.

Parameter Comparison

Engineering Selection Recommendations

For direct replacement of discontinued CD74AC00M units:

CD74AC00M96 provides the closest electrical match with identical voltage supply range (1.5V ~ 5.5V) and propagation delay (7.3ns). This Texas Instruments part maintains full compatibility with the original specification and is available in active production status with Tape & Reel packaging.

For applications requiring extended temperature range (-55°C ~ 125°C) with alternative packaging options, MC74AC00DR2G (onsemi, Tape & Reel) and MC74AC00DG (onsemi, Tube) are functionally equivalent with 1ns additional propagation delay tolerance.

For cost-optimized procurement with standard industrial temperature range (-40°C ~ 85°C), SN74AC00DR (Texas Instruments, Cut Tape & Digi-Reel) and 74AC00SCX (onsemi, Cut Tape & Digi-Reel) are suitable alternatives with reduced quiescent current (2 µA).

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and identical 14-SOIC package dimensions.

Frequently Asked Questions (FAQ)

Q: Can I use SN74AC00DR as a direct replacement for CD74AC00M?

A: SN74AC00DR is functionally compatible for most applications. The key differences are: voltage supply range (2V ~ 6V vs. 1.5V ~ 5.5V), operating temperature range (-40°C ~ 85°C vs. -55°C ~ 125°C), and propagation delay (8ns vs. 7.3ns). If your application operates above 2V and within -40°C ~ 85°C, this part is suitable. For extended temperature or lower voltage operation, use CD74AC00M96 or MC74AC00DR2G.

Q: What is the difference between Tube, Tape & Reel, and Cut Tape packaging?

A: Packaging affects order quantity and handling. Tube packaging is for smaller quantities and manual handling. Tape & Reel is for automated assembly with standard reel quantities. Cut Tape & Digi-Reel provides flexibility between manual and automated processes. All three packaging options contain identical die and electrical performance.

Q: Are onsemi and Texas Instruments parts interchangeable?

A: Yes, for this 74AC00 logic gate series. Both manufacturers produce functionally equivalent parts with identical pin configurations and logic function. The 14-SOIC package dimensions are identical. Verify operating temperature and voltage supply requirements match your application specifications.

Q: Why does CD74AC00M96 have the same electrical specs as CD74AC00M?

A: CD74AC00M96 is the active production variant of the same base product (74AC00). The "96" suffix indicates Tape & Reel packaging, while the original CD74AC00M uses Tube packaging. Electrical performance and die specifications are identical.

Q: Can I substitute parts with different propagation delays?

A: The difference between 7.3ns and 8ns propagation delay is within standard logic IC tolerance and acceptable for most digital applications. If your design has critical timing requirements with less than 0.7ns margin, verify the specific propagation delay specification against your circuit requirements before substitution.
