MC74ACT10DR2G NAND Gate IC Equivalent & Substitute Parts

Part Overview

The MC74ACT10DR2G is a 3-channel NAND gate logic IC manufactured by onsemi, housed in a 14-SOIC surface mount package. This part is currently in active production status with 973 units in stock. The MC74ACT10DR2G operates within the 74ACT logic family standard, providing three independent 3-input NAND gate circuits suitable for digital logic applications requiring standard TTL-compatible switching speeds and power consumption characteristics.

Substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design requirements necessitate extended operating temperature ranges or different compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MC74ACT10DR2G is determined by strict equivalence across the following critical parameters: logic type (NAND gate), circuit count (3 channels), input count per gate (3 inputs), supply voltage range (4.5V to 5.5V), output current capability (24mA), input logic thresholds (0.8V low, 2V high), package type (14-SOIC), and surface mount mounting type.

Parts are classified into two substitution categories:

Direct Substitutes maintain identical electrical specifications including propagation delay (9ns @ 5V, 50pF) and operating temperature range (-40°C to 85°C). These parts are pin-compatible and functionally equivalent with no design modifications required.

Similar Substitutes share the same logic function, circuit count, input configuration, and package type but differ in propagation delay (14.6ns @ 5V, 50pF) and/or operating temperature range (-55°C to 125°C). These parts are electrically compatible but may require timing verification in speed-critical applications and offer extended temperature operation for specialized environments.

Parameter Comparison

Engineering Selection Recommendations

SN74ACT10DR is the primary direct substitute for MC74ACT10DR2G. Both parts maintain identical electrical performance with 9ns propagation delay and -40°C to 85°C operating range. SN74ACT10DR is manufactured by Texas Instruments, carries active product status, and is ROHS3 compliant. Tape & Reel packaging matches the original specification. This part is suitable for direct replacement in all applications without design modification.

SN74ACT10D is a direct electrical equivalent available from Texas Instruments in Tube packaging. It carries Last Time Buy status, indicating limited future availability. This part is appropriate for applications where Tube packaging is acceptable and where long-term supply is not a critical requirement.

CD74ACT10M96 is a similar substitute suitable for applications requiring extended operating temperature range (-55°C to 125°C). This part exhibits 14.6ns propagation delay compared to the 9ns specification of the primary part. CD74ACT10M96 is manufactured by Texas Instruments, maintains active product status, and is ROHS3 compliant. Selection of this part requires verification that the increased propagation delay does not violate system timing requirements.

CD74ACT10M is a similar substitute manufactured by Harris Corporation with obsolete product status and RoHS non-compliance. This part should not be selected for new designs or applications requiring RoHS certification. The extended operating temperature range (-55°C to 125°C) and increased propagation delay (14.6ns) are the only technical advantages, which do not justify the compliance and availability disadvantages.

Frequently Asked Questions (FAQ)

Q: Can SN74ACT10DR be used as a direct replacement for MC74ACT10DR2G without circuit modifications?

A: Yes. SN74ACT10DR maintains identical electrical specifications including supply voltage (4.5V to 5.5V), output current (24mA), propagation delay (9ns @ 5V, 50pF), and operating temperature range (-40°C to 85°C). The 14-SOIC package and pin configuration are identical. No circuit modifications are required.

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

A: Tape & Reel packaging is used for automated assembly processes where components are fed from continuous tape reels. Tube packaging contains loose components in plastic tubes and is used for manual assembly or lower-volume production. Both packaging formats contain identical die and electrical performance.

Q: Why does CD74ACT10M96 have a longer propagation delay than MC74ACT10DR2G?

A: CD74ACT10M96 is specified for extended operating temperature range (-55°C to 125°C) compared to MC74ACT10DR2G (-40°C to 85°C). The 14.6ns propagation delay at 5V and 50pF load reflects the broader temperature specification. This is a manufacturing characteristic of the extended-temperature variant.

Q: Is CD74ACT10M suitable for new designs?

A: No. CD74ACT10M carries obsolete product status and is RoHS non-compliant. New designs should not incorporate this part. Existing designs using CD74ACT10M should transition to CD74ACT10M96 or SN74ACT10DR for compliance and long-term availability.

Q: What are the input logic thresholds for all substitute parts?

A: All substitute parts maintain identical input logic thresholds: Low input 0.8V maximum, High input 2V minimum. These thresholds are standard across the 74ACT logic family and ensure compatibility with TTL-level digital signals.

Q: Can substitute parts be mixed in the same design?

A: Yes, provided that timing requirements are satisfied. If the design uses only SN74ACT10DR or MC74ACT10DR2G (9ns propagation delay), these parts are interchangeable. If CD74ACT10M96 (14.6ns propagation delay) is introduced, system timing analysis must confirm that the increased delay does not violate setup/hold time or frequency specifications.
