74AC10PC NAND Gate IC Equivalent & Substitute Parts

Part Overview

The 74AC10PC is a NAND Gate IC featuring 3 channels with 3 inputs per channel, manufactured by onsemi in a 14-MDIP package. This logic component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The 74AC series represents a standard logic family widely used in digital circuit applications requiring NAND gate functionality with moderate propagation delay and power consumption characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 74AC10PC is determined by the following critical parameters:

• Logic Function: NAND gate with 3 channels and 3 inputs per channel
• Package Compatibility: 14-DIP form factor with 0.300" (7.62mm) pitch for through-hole mounting
• Electrical Performance: Supply voltage range, quiescent current, output drive capability, and propagation delay
• Operating Temperature Range: Functional performance across specified temperature extremes

The substitute parts identified maintain compatibility across these core parameters while originating from different manufacturers within the 74AC logic family. Variations in supply voltage range, quiescent current specifications, and propagation delay do not preclude functional substitution when the application requirements fall within the overlapping parameter windows.

Engineering Selection Recommendations

SN74AC10N (Texas Instruments) is the preferred substitute for new designs and ongoing procurement. This part maintains identical electrical specifications to the 74AC10PC across supply voltage, quiescent current, output drive, and propagation delay. The SN74AC10N carries Active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment. Pin-compatible 14-DIP packaging enables direct board-level substitution without layout modification.

CD74AC10E (Harris Corporation) provides functional equivalence with extended operating temperature range (-55°C ~ 125°C) and wider supply voltage tolerance (1.5V ~ 5.5V). However, this part is classified as obsolete and exhibits higher quiescent current (4 µA maximum) and slower propagation delay (12.2ns at 5V, 50pF) compared to the primary part. The CD74AC10E is suitable for applications where extended temperature performance is required and timing margins accommodate the increased propagation delay. RoHS non-compliance status may restrict use in regulated applications.

Frequently Asked Questions (FAQ)

Q: Can SN74AC10N be used as a direct replacement for 74AC10PC?

A: Yes. Both parts share identical electrical specifications for supply voltage (2V ~ 6V), quiescent current (2 µA maximum), output drive capability (24mA), and propagation delay (7ns at 5V, 50pF). The 14-DIP package pinout is identical, enabling direct substitution without circuit modification.

Q: What are the key differences between CD74AC10E and the primary part?

A: The CD74AC10E operates across a wider supply voltage range (1.5V ~ 5.5V versus 2V ~ 6V) and extended temperature range (-55°C ~ 125°C versus -40°C ~ 85°C). Quiescent current is higher at 4 µA maximum, and propagation delay is slower at 12.2ns. These differences do not affect functional compatibility but may impact power consumption and timing-critical applications.

Q: Are all substitute parts available in the same package?

A: Yes. All three parts use the 14-DIP (0.300", 7.62mm) through-hole package, ensuring mechanical and electrical compatibility on standard DIP sockets and PCB layouts.

Q: What is the significance of product status in selecting a substitute?

A: SN74AC10N carries Active status, indicating current manufacturing and long-term availability. Both 74AC10PC and CD74AC10E are obsolete, meaning production has ceased. For new designs, Active parts provide supply chain stability and regulatory compliance assurance.

Q: Does RoHS compliance affect substitution decisions?

A: RoHS compliance status reflects regulatory requirements for hazardous substance restrictions. SN74AC10N is ROHS3 compliant, supporting use in regulated markets. CD74AC10E is RoHS non-compliant, which may restrict deployment in applications subject to RoHS directives.
