74ACT10SC NAND Gate IC Equivalent & Substitute Parts

Part Overview

The 74ACT10SC is a NAND Gate IC featuring 3 channels with 3 inputs per channel, packaged in a 14-SOIC surface mount configuration. Manufactured by onsemi, this logic component operates within the 4.5V to 5.5V supply voltage range and is classified as obsolete. Due to its obsolete status and limited availability relative to active alternatives, identifying equivalent substitute parts is necessary for design continuity and procurement flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74ACT10SC are classified based on electrical parameter compatibility and packaging equivalence. All substitute candidates maintain identical logic configuration (3 channels, 3 inputs per channel), supply voltage range (4.5V ~ 5.5V), output current specifications (24mA high/low), and input logic thresholds (0.8V low, 2V high). The 14-SOIC package is consistent across all alternatives.

Substitutes are grouped into three categories:

Direct Manufacturer Equivalents: Parts with identical propagation delay (9ns @ 5V, 50pF) and operating temperature range (-40°C ~ 85°C). These provide pin-for-pin and functional equivalence with no design modifications required.

Similar Functional Equivalents: Parts with extended operating temperature range (-55°C ~ 125°C) and increased propagation delay (14.6ns @ 5V, 50pF). These maintain full electrical compatibility but operate across a wider temperature spectrum with slightly degraded timing performance.

Parametric Equivalents: Parts meeting all core electrical specifications with identical propagation delay and operating temperature, available in alternative packaging formats.

Parameter Comparison

Engineering Selection Recommendations

For timing-critical applications requiring 9ns propagation delay: Select SN74ACT10DR (Texas Instruments, Active status, 3230 pcs inventory) or MC74ACT10DR2G (onsemi, Active status, 973 pcs inventory). Both parts maintain identical timing specifications to the original 74ACT10SC and are actively manufactured, ensuring long-term availability.

For extended temperature range applications (-55°C ~ 125°C): Select CD74ACT10M96 (Texas Instruments, Active status, ROHS3 Compliant). This part accommodates wider operating temperatures while maintaining active production status and regulatory compliance.

For applications with relaxed timing constraints: CD74ACT10M (Harris Corporation) provides extended temperature operation but carries obsolete status and RoHS non-compliance, limiting suitability for new designs.

For inventory optimization: SN74ACT10D (Texas Instruments, Last Time Buy status, 2260 pcs) offers timing equivalence to the original part but with limited future availability due to last-time-buy designation.

All recommended active-status alternatives maintain the 14-SOIC package footprint, supply voltage range (4.5V ~ 5.5V), output current (24mA), and input logic thresholds, ensuring direct functional substitution without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can SN74ACT10DR be used as a direct replacement for 74ACT10SC?

A: Yes. SN74ACT10DR maintains identical electrical specifications: 9ns propagation delay @ 5V with 50pF load, -40°C to 85°C operating temperature, 4.5V to 5.5V supply voltage, 24mA output current, and 14-SOIC package. Pin configuration and logic function are equivalent.

Q: What is the difference between the 9ns and 14.6ns propagation delay variants?

A: Parts with 14.6ns propagation delay (CD74ACT10M96, CD74ACT10M) operate across an extended temperature range (-55°C ~ 125°C) compared to the standard -40°C ~ 85°C range. The increased delay reflects timing characteristics at temperature extremes. Select 14.6ns variants only if extended temperature operation is required.

Q: Are all substitute parts RoHS compliant?

A: Active-status substitutes (SN74ACT10DR, MC74ACT10DR2G, CD74ACT10M96, SN74ACT10D) are ROHS3 Compliant. CD74ACT10M is RoHS non-compliant and obsolete, unsuitable for new designs subject to RoHS requirements.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel (TR) and Tube packaging formats contain identical die and electrical specifications. Packaging selection depends on procurement volume and assembly line requirements, not circuit performance.

Q: Which substitute offers the best long-term availability?

A: SN74ACT10DR (Texas Instruments, Active status, 3230 pcs inventory) provides the highest inventory level and active manufacturing status, ensuring sustained availability for production requirements.
