CD74AC10ME4 Equivalent & Substitute Parts

Part Overview

The CD74AC10ME4 is a NAND Gate IC featuring 3 channels with 3 inputs per channel in a 14-SOIC surface mount package, manufactured by Texas Instruments. This logic component operates across a supply voltage range of 1.5V to 5.5V and is designed for general-purpose digital logic applications requiring NAND gate functionality.

The CD74AC10ME4 carries a Last Time Buy status, indicating that Texas Instruments has discontinued active production. This necessitates identifying equivalent substitute parts that maintain functional and electrical compatibility while ensuring continued design support and component availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD74AC10ME4 is determined by the following critical parameters:

• Logic configuration: 3-channel NAND gate with 3 inputs per channel
• Package type: 14-SOIC surface mount form factor
• Electrical performance: Output drive capability (24mA minimum), quiescent current (4 µA maximum)
• Supply voltage compatibility: Minimum 1.5V operation required
• Operating temperature range: Minimum -55°C to 125°C coverage
• Compliance: ROHS3 compliance and MSL Level 1 rating

Substitute parts must maintain identical logic architecture, pinout compatibility through the 14-SOIC package, and equivalent electrical performance characteristics. Variations in supply voltage range, operating temperature limits, or propagation delay do not preclude substitution provided the substitute meets or exceeds the application requirements.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the CD74AC10ME4, the following selection criteria apply based on product status and compliance:

CD74AC10M96 is the primary recommended substitute. This part maintains Texas Instruments manufacturing continuity, carries Active product status ensuring long-term availability, and is available in Tape & Reel packaging for production environments. All electrical parameters remain identical to the CD74AC10ME4, with ROHS3 compliance and MSL Level 1 rating preserved.

MC74AC10DR2G provides an alternative from onsemi with Active product status and Tape & Reel packaging. This substitute offers improved propagation delay performance (7ns versus 12.2ns) and extended supply voltage range (2V to 6V). The operating temperature range is narrower (-40°C to 85°C) compared to the CD74AC10ME4 (-55°C to 125°C), which may limit suitability for extreme temperature applications. ROHS3 compliance and MSL Level 1 rating are maintained.

MC74AC10DG is available from onsemi in Tube packaging with identical electrical and compliance characteristics to MC74AC10DR2G, suitable for lower-volume or prototype applications.

CD74AC10M carries Obsolete status and should be avoided for new designs despite electrical equivalence.

Frequently Asked Questions (FAQ)

Q: Can CD74AC10M96 directly replace CD74AC10ME4 in existing designs?

A: Yes. CD74AC10M96 maintains identical logic configuration (3-channel NAND gate, 3 inputs), electrical performance (24mA output drive, 4 µA quiescent current, 12.2ns propagation delay at 5V), operating temperature range (-55°C to 125°C), and 14-SOIC package pinout. The primary difference is packaging format (Tape & Reel versus Tube) and Active product status.

Q: What is the difference between MC74AC10DG and MC74AC10DR2G?

A: Both parts are functionally equivalent onsemi NAND gate ICs with identical electrical specifications. The distinction is packaging: MC74AC10DG is supplied in Tube format for lower-volume applications, while MC74AC10DR2G is supplied in Tape & Reel format for automated production assembly. Both carry Active product status and ROHS3 compliance.

Q: Are there temperature range limitations when substituting with onsemi parts?

A: MC74AC10DG and MC74AC10DR2G operate across -40°C to 85°C, which is narrower than the CD74AC10ME4 range of -55°C to 125°C. Applications requiring operation below -40°C or above 85°C must use Texas Instruments alternatives (CD74AC10M96 or CD74AC10M).

Q: Does the improved propagation delay of onsemi parts affect compatibility?

A: No. The onsemi parts (MC74AC10DG and MC74AC10DR2G) feature 7ns propagation delay compared to 12.2ns for Texas Instruments parts. Faster propagation delay is a performance enhancement that does not compromise compatibility. Applications designed for 12.2ns timing will operate correctly with 7ns parts.

Q: What packaging considerations apply to production environments?

A: For automated assembly, Tape & Reel packaging (CD74AC10M96 or MC74AC10DR2G) is standard. Tube packaging (CD74AC10ME4, CD74AC10M, or MC74AC10DG) is suitable for manual assembly, prototyping, or lower-volume production runs. Packaging selection does not affect electrical performance or compatibility.

Q: Why is CD74AC10M not recommended despite electrical equivalence?

A: CD74AC10M carries Obsolete product status, indicating discontinued manufacturing and limited future availability. For new designs or long-term production support, Active status parts (CD74AC10M96, MC74AC10DG, MC74AC10DR2G) are preferred to ensure supply chain continuity.
