74AC11PC Equivalent & Substitute Parts

Part Overview

The 74AC11PC is a 3-channel AND gate logic IC manufactured by onsemi, housed in a 14-pin MDIP package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The 74AC11 series provides standard AND gate functionality suitable for digital logic applications requiring low-power operation and reliable switching characteristics across industrial temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74AC11PC is determined by strict equivalence across the following critical parameters:

• Logic Function: AND Gate with 3 channels and 3 inputs per channel
• Electrical Performance: Identical supply voltage range (2V ~ 6V), quiescent current (2 µA max), output drive capability (24mA), input logic thresholds, and propagation delay (8ns @ 5V, 50pF)
• Operating Temperature Range: -40°C ~ 85°C
• Package Compatibility: 14-pin DIP form factor with 0.300" (7.62mm) pitch
• Base Series: 74AC logic family

The SN74AC11N from Texas Instruments meets all these criteria as a parametric equivalent, with identical electrical specifications and compatible through-hole DIP packaging. The primary distinction is product status and packaging format (tube vs. standard packaging).

Engineering Selection Recommendations

The SN74AC11N from Texas Instruments is the direct parametric equivalent for the obsolete 74AC11PC. Selection of this substitute is based on:

• Product Status: The SN74AC11N maintains active production status, ensuring long-term availability and supply chain reliability compared to the obsolete 74AC11PC.
• Regulatory Compliance: The SN74AC11N is ROHS3 compliant, meeting current environmental and regulatory requirements. Both parts maintain REACH Unaffected status and EAR99 export classification.
• Electrical Equivalence: All functional and electrical parameters are identical, enabling direct substitution without circuit redesign.
• Package Compatibility: Both parts use identical 14-DIP through-hole packaging with 0.300" pitch, supporting direct PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can the SN74AC11N replace the 74AC11PC in existing designs?

A: Yes. The SN74AC11N is a parametric equivalent with identical electrical specifications, operating temperature range, and DIP package dimensions. Direct substitution is supported without circuit modification.

Q: What are the key differences between these parts?

A: The primary differences are manufacturer (onsemi vs. Texas Instruments), product status (obsolete vs. active), and packaging format (standard vs. tube). Electrical performance and pin configuration are identical.

Q: Are there any compliance considerations for substitution?

A: The SN74AC11N is ROHS3 compliant, providing enhanced regulatory compliance compared to the obsolete 74AC11PC. Both parts are REACH unaffected and classified as EAR99 for export purposes.

Q: Does the package format affect compatibility?

A: No. Both the 74AC11PC and SN74AC11N use 14-pin DIP packaging with 0.300" (7.62mm) pitch. PCB footprints and through-hole mounting are fully compatible.

Q: What is the propagation delay specification?

A: Both parts specify a maximum propagation delay of 8 nanoseconds at 5V supply voltage with a 50pF load, ensuring equivalent switching performance in digital logic applications.
