74ACT04PC Equivalent & Substitute Parts

Part Overview

The 74ACT04PC is a 6-channel inverter logic IC manufactured by onsemi in a 14-MDIP package. This component performs basic logic inversion operations and is classified as obsolete. Due to its obsolete status, identifying functionally equivalent substitute parts is essential for design continuity, procurement flexibility, and long-term product support.

Substitute Part Grouping Explanation

Substitute parts for the 74ACT04PC are identified based on strict equivalence across the following critical parameters:

• Logic Type: Inverter
• Number of Circuits: 6
• Number of Inputs: 1
• Voltage - Supply: 4.5V ~ 5.5V
• Current - Output High, Low: 24mA, 24mA
• Input Logic Level - Low: 0.8V
• Input Logic Level - High: 2V
• Package / Case: 14-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole

All identified substitutes maintain these core electrical and mechanical specifications, ensuring functional compatibility in circuit applications. Variations in secondary parameters such as quiescent current, propagation delay, operating temperature range, and product status are noted but do not preclude substitution where the primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

CD74ACT04E (Harris Corporation): This part is a direct manufacturer equivalent with identical electrical specifications to the 74ACT04PC. However, it carries obsolete product status and RoHS non-compliant certification. Selection of this substitute is appropriate only when legacy compliance requirements are not applicable and existing inventory is available.

SN74ACT04N (Texas Instruments): This part is a parametric equivalent with active product status and ROHS3 compliance certification. The SN74ACT04N demonstrates superior quiescent current performance (2 µA versus 4 µA) and maintains identical propagation delay characteristics. This part is the preferred substitute for new designs and applications requiring current regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the CD74ACT04E and SN74ACT04N be used interchangeably with the 74ACT04PC?

A: Yes. Both substitutes maintain electrical equivalence across all critical parameters including supply voltage, output current, input logic levels, and propagation delay. Physical package dimensions and through-hole mounting are identical, enabling direct pin-compatible replacement.

Q: What is the significance of the different operating temperature ranges?

A: The CD74ACT04E operates across -55°C to 125°C, while the 74ACT04PC and SN74ACT04N operate across -40°C to 85°C. Temperature range differences do not affect substitution compatibility unless the application requires operation outside the -40°C to 85°C window. In such cases, the CD74ACT04E provides extended temperature capability.

Q: Why is the SN74ACT04N recommended for new designs?

A: The SN74ACT04N carries active product status and ROHS3 compliance certification, ensuring long-term availability and regulatory alignment. It also demonstrates lower quiescent current consumption, reducing power dissipation in battery-powered or power-sensitive applications.

Q: Are there any package or mounting differences between these parts?

A: No. All three parts use identical 14-DIP (0.300", 7.62mm) packaging with through-hole mounting. Direct socket substitution is possible without PCB modification.

Q: What does the propagation delay difference between 74ACT04PC (8.5ns) and CD74ACT04E (9.3ns) mean for circuit performance?

A: The 0.8ns difference is negligible in most digital logic applications. Substitution is appropriate unless the design operates at frequencies where sub-nanosecond timing margins are critical. In standard TTL/CMOS logic circuits, this variation is within acceptable tolerance.
