74ACTQ10PC NAND Gate IC Equivalent & Substitute Parts

Part Overview

The 74ACTQ10PC is a NAND Gate IC featuring 3 channels with 3 inputs per channel, manufactured by onsemi in a 14-MDIP package. This logic component operates within the 4.5V to 5.5V supply voltage range and is designed for through-hole mounting applications. The product is currently obsolete, making equivalent substitute parts necessary for legacy system maintenance, repair, and redesign applications where functional compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74ACTQ10PC are qualified based on the following criteria:

• Identical logic function: NAND Gate with 3 channels and 3 inputs per channel
• Compatible supply voltage range: 4.5V ~ 5.5V
• Matching output current specifications: 24mA high and low
• Identical input logic levels: 0.8V low threshold, 2V high threshold
• Through-hole mounting in 14-DIP package format (0.300", 7.62mm)
• Functional pin compatibility within the 14-pin DIP footprint

Parts meeting these criteria are electrically and mechanically interchangeable in applications designed for the 74ACTQ10PC.

Parameter Comparison

Engineering Selection Recommendations

SN74ACT10N (Texas Instruments) is the primary substitute for new designs and ongoing production applications. This part maintains active product status, ensuring continued availability and manufacturer support. It meets all electrical and mechanical compatibility requirements with propagation delay of 9ns at 5V and 50pF load, positioning it between the original 74ACTQ10PC and the CD74ACT10E. The SN74ACT10N is RoHS3 compliant, supporting modern supply chain and environmental compliance requirements.

CD74ACT10E (Harris Corporation) serves as an alternative substitute where extended operating temperature range (-55°C ~ 125°C) is required. This part is obsolete but remains available in inventory. The propagation delay of 14.6ns is acceptable for non-timing-critical applications. Note that this part is RoHS non-compliant and should be evaluated against project compliance requirements.

Both substitute parts are electrically and mechanically compatible with the 74ACTQ10PC within the specified parameter ranges. Selection between them depends on product status requirements, compliance certifications, and application-specific performance criteria.

Frequently Asked Questions (FAQ)

Q: Can the SN74ACT10N directly replace the 74ACTQ10PC in existing designs?

A: Yes. The SN74ACT10N is electrically and mechanically compatible. Both parts feature identical logic function (3-channel NAND gate with 3 inputs), matching supply voltage (4.5V ~ 5.5V), output current (24mA), input logic levels, and 14-DIP package footprint. The propagation delay difference (9ns vs 7.5ns) is within acceptable tolerance for most applications.

Q: What is the difference in propagation delay between these parts?

A: The 74ACTQ10PC has a maximum propagation delay of 7.5ns at 5V with 50pF load. The SN74ACT10N is 9ns, and the CD74ACT10E is 14.6ns. For timing-critical applications, verify that the substitute part's delay specification meets system requirements.

Q: Are there package compatibility concerns?

A: No. All three parts use the 14-DIP (0.300", 7.62mm) through-hole package. Pin assignments are identical, allowing direct socket substitution without PCB modification.

Q: Which substitute should be used for new production?

A: The SN74ACT10N is recommended for new production due to its active product status and RoHS3 compliance. This ensures long-term availability and alignment with current environmental and supply chain standards.

Q: Can the CD74ACT10E be used in temperature-critical applications?

A: The CD74ACT10E operates across -55°C ~ 125°C, compared to -40°C ~ 85°C for the 74ACTQ10PC and SN74ACT10N. If your application requires extended temperature range, the CD74ACT10E is suitable. However, verify that other system components support this temperature range.

Q: What compliance certifications apply to these parts?

A: The SN74ACT10N is RoHS3 compliant and REACH unaffected. The CD74ACT10E is RoHS non-compliant. The 74ACTQ10PC is REACH unaffected. Verify compliance requirements for your specific application before selection.
