74AC10SC NAND Gate IC Equivalent & Substitute Parts

Part Overview

The 74AC10SC is a triple 3-input NAND gate logic IC manufactured by onsemi in 14-SOIC surface mount packaging. This part is currently obsolete, making equivalent and substitute parts necessary for ongoing design support and production requirements. The 74AC10 series represents a standard logic function across multiple manufacturers, with several active alternatives available that maintain functional compatibility within specified electrical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 74AC10SC is determined by strict equivalence across the following critical parameters: logic function (NAND gate), circuit count (3 channels), input count (3 inputs per channel), package type (14-SOIC), and electrical performance specifications (voltage supply, output current, propagation delay, and operating temperature range).

Substitute parts are grouped into two categories:

Direct Manufacturer Equivalents maintain identical electrical specifications and package dimensions, differing only in product status or packaging format (tube, tape & reel, or cut tape).

Parametric Equivalents provide the same logic function and package but may have extended voltage supply ranges, higher quiescent current, or different propagation delay characteristics. These parts are functionally compatible but operate under different electrical constraints.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: SN74AC10DR (Texas Instruments)

SN74AC10DR is the preferred substitute for 74AC10SC. It maintains identical electrical specifications (2V to 6V supply, 2 µA quiescent current, 7ns propagation delay, -40°C to 85°C operating range) and 14-SOIC package dimensions. The part is currently active with established supply availability. RoHS3 compliance and REACH unaffected status align with modern manufacturing standards.

Secondary Recommendation: MC74AC10DR2G (onsemi)

MC74AC10DR2G provides direct manufacturer continuity from the original 74AC10SC. Electrical performance is equivalent (7ns propagation delay, identical package), with the trade-off of slightly elevated quiescent current (4 µA versus 2 µA). Active product status and tape & reel packaging support high-volume production. RoHS3 compliant.

Alternative for Extended Temperature Range: CD74AC10M96 (Texas Instruments)

CD74AC10M96 extends the operating temperature range to -55°C to 125°C and supports lower supply voltage operation (1.5V minimum). Propagation delay increases to 12.2ns at 5V. This part is suitable for applications requiring wider temperature specifications. Currently active with tape & reel packaging.

Package Consideration: SN74AC10NSR (Texas Instruments)

SN74AC10NSR maintains identical electrical specifications to SN74AC10DR but uses 14-SO packaging (0.209", 5.30mm width) instead of 14-SOIC (0.154", 3.90mm width). This part is suitable only if PCB layout accommodates the wider package footprint.

Frequently Asked Questions (FAQ)

Q: Can I use MC74AC10DR2G as a direct replacement for 74AC10SC?

A: Yes. MC74AC10DR2G is functionally equivalent with identical propagation delay (7ns) and package type (14-SOIC). The quiescent current specification is higher (4 µA versus 2 µA), which has negligible impact on most applications. Active product status ensures supply availability.

Q: What is the difference between SN74AC10D and SN74AC10DR?

A: Both parts are electrically identical (2V to 6V supply, 2 µA quiescent current, 7ns propagation delay). SN74AC10D is discontinued at DiGi Electronics, while SN74AC10DR remains active. SN74AC10DR is the recommended choice for new designs and ongoing production.

Q: Why does CD74AC10M96 have different electrical specifications?

A: CD74AC10M96 is designed for extended operating conditions. The lower supply voltage minimum (1.5V versus 2V) and wider temperature range (-55°C to 125°C versus -40°C to 85°C) result in higher propagation delay (12.2ns versus 7ns). Select this part only if your application requires these extended specifications.

Q: Is the package difference between 14-SOIC and 14-SO significant?

A: Yes. 14-SOIC (0.154" width) and 14-SO (0.209" width) have different footprints. SN74AC10NSR uses the wider 14-SO package and requires PCB layout verification before substitution. Confirm your PCB design accommodates the larger package dimensions.

Q: Are all substitute parts RoHS3 compliant?

A: All active substitute parts listed (MC74AC10DR2G, MC74AC10DG, SN74AC10DR, CD74AC10M96, SN74AC10NSR) are RoHS3 compliant. The obsolete parts (74AC10SC, SN74AC10D, CD74AC10M) have varying compliance status. For new production, select from active parts to ensure regulatory compliance.

Q: What is the inventory status for these parts?

A: MC74AC10DR2G (5846 pcs), CD74AC10M96 (3506 pcs), SN74AC10NSR (3040 pcs), and SN74AC10DR (2846 pcs) have established inventory levels. MC74AC10DG (2328 pcs) and SN74AC10D (1147 pcs) have lower availability. Verify current stock with your supplier before finalizing procurement decisions.
