74ACTQ00PC NAND Gate IC Equivalent & Substitute Parts

Part Overview

The 74ACTQ00PC is a 4-channel 2-input NAND gate logic IC manufactured by onsemi in 14-MDIP packaging. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The 74ACTQ00PC operates within the 74ACT logic family standard, which defines compatible electrical and mechanical parameters for direct substitution across qualified alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74ACTQ00PC is determined by strict adherence to the following criteria:

• Logic Function: All substitutes must implement 4-channel 2-input NAND gate logic
• Electrical Specifications: Supply voltage range (4.5V ~ 5.5V), output current (24mA, 24mA), and input logic levels (Low: 0.8V, High: 2V) must be identical
• Package Compatibility: All substitutes must use 14-DIP (0.300", 7.62mm) through-hole packaging to ensure mechanical and electrical compatibility with existing PCB layouts
• Base Product Number: Substitutes belong to the 74ACT00 family, ensuring functional equivalence within the 74ACT logic series

The identified substitutes (CD74ACT00E and SN74ACT00N) meet all mandatory electrical and mechanical parameters for direct replacement.

Engineering Selection Recommendations

SN74ACT00N (Texas Instruments) is the primary substitute for the 74ACTQ00PC. This part maintains identical electrical specifications (supply voltage, output current, input logic levels, and operating temperature range) while offering active product status and RoHS3 compliance. The propagation delay of 9ns falls between the original specification (7.5ns) and the Harris alternative, providing acceptable performance for most applications within the 74ACT logic family.

CD74ACT00E (Harris Corporation) serves as a secondary substitute. While electrically compatible across all critical parameters, this part is classified as obsolete and exhibits higher quiescent current (4 µA vs. 2 µA) and longer propagation delay (13.2ns). The extended operating temperature range (-55°C ~ 125°C) provides additional thermal margin for specialized applications. This part is RoHS non-compliant.

Both substitutes are mechanically and electrically interchangeable with the 74ACTQ00PC in 14-DIP through-hole applications.

Frequently Asked Questions (FAQ)

Q: Can the CD74ACT00E and SN74ACT00N be used interchangeably with the 74ACTQ00PC?

A: Both parts meet the mandatory electrical and mechanical substitution criteria. The SN74ACT00N is preferred due to active product status and RoHS compliance. The CD74ACT00E is functionally compatible but obsolete and non-compliant.

Q: What is the significance of propagation delay differences (7.5ns vs. 9ns vs. 13.2ns)?

A: Propagation delay determines signal transition speed through the logic gate. The SN74ACT00N (9ns) and 74ACTQ00PC (7.5ns) are suitable for timing-critical applications. The CD74ACT00E (13.2ns) may require timing analysis in high-speed circuits.

Q: Are all three parts compatible with existing 14-DIP PCB layouts?

A: Yes. All three parts use identical 14-DIP (0.300", 7.62mm) through-hole packaging and pin configuration, ensuring direct mechanical compatibility without PCB modification.

Q: What is the difference between the 74ACTQ and 74ACT series designations?

A: Both belong to the 74ACT logic family with identical electrical specifications. The "Q" suffix in 74ACTQ indicates a specific manufacturing variant by onsemi. The base function (74ACT00) remains consistent across all variants.

Q: Which substitute should be selected for new designs?

A: The SN74ACT00N is the recommended choice for new designs, as it maintains active product status, offers RoHS3 compliance, and provides performance within acceptable parameters for the 74ACT logic family.
