74ACT11004N Equivalent & Substitute Parts

Part Overview

The 74ACT11004N is a 6-channel inverter logic IC manufactured by Texas Instruments in a 20-DIP through-hole package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and production continuity. The 74ACT series provides standard inverter functionality with TTL-compatible logic levels and is commonly used in digital logic applications requiring signal inversion across multiple channels.

Substitute Part Grouping Explanation

The SN74ACT04PWR qualifies as a functional equivalent to the 74ACT11004N based on the following matching parameters:

• Identical logic type (Inverter) and circuit configuration (6 channels, 1 input per channel)
• Matching supply voltage range (4.5V ~ 5.5V)
• Identical output current specifications (24mA, 24mA)
• Matching input logic levels (Low: 0.8V, High: 2V)
• Equivalent propagation delay performance (8.5ns vs 9ns @ 5V, 50pF)
• Identical operating temperature range (-40°C ~ 85°C)
• Same RoHS3 compliance status

The primary difference is packaging: the 74ACT11004N uses a 20-DIP through-hole package, while the SN74ACT04PWR uses a 14-TSSOP surface-mount package. This substitution requires PCB layout redesign but maintains full electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The SN74ACT04PWR is the recommended substitute for the obsolete 74ACT11004N. Both components maintain identical electrical specifications and are manufactured by Texas Instruments under the same 74ACT logic family. The SN74ACT04PWR offers the additional advantage of active product status, ensuring continued availability and manufacturing support.

The SN74ACT04PWR demonstrates improved quiescent current performance (2 µA vs 4 µA) and faster propagation delay (8.5ns vs 9ns), providing marginal performance benefits. Both components carry ROHS3 compliance and are suitable for applications requiring RoHS-compliant components.

Selection between these parts depends on packaging requirements: retain the 74ACT11004N only if through-hole mounting is mandatory; otherwise, transition to the SN74ACT04PWR for new designs to ensure long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the SN74ACT04PWR directly replace the 74ACT11004N on existing PCBs?

A: Electrical substitution is complete. However, physical replacement requires PCB redesign due to different package types (20-DIP through-hole vs 14-TSSOP surface-mount). Pin-to-pin correspondence differs between packages.

Q: What are the key compatibility criteria for this substitution?

A: Compatibility is based on matching logic type (inverter), circuit count (6 channels), supply voltage (4.5V ~ 5.5V), output current (24mA), input logic levels (0.8V low, 2V high), and operating temperature range (-40°C ~ 85°C). All criteria are met by the SN74ACT04PWR.

Q: Why is the 74ACT11004N obsolete?

A: The 74ACT11004N is classified as obsolete by the manufacturer. The SN74ACT04PWR represents the active product line continuation within the 74ACT inverter family.

Q: Are there differences in moisture sensitivity between these parts?

A: The 74ACT11004N lists moisture sensitivity as not applicable. The SN74ACT04PWR carries MSL 1 (unlimited), indicating minimal moisture sensitivity risk for surface-mount handling and storage.

Q: Does the faster propagation delay of the SN74ACT04PWR affect system compatibility?

A: The SN74ACT04PWR propagation delay (8.5ns) is faster than the 74ACT11004N (9ns). This represents an improvement and does not create compatibility issues in systems designed for the original part's timing specifications.
