Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74F11PC is determined by strict equivalence across the following critical parameters:

• Logic Function: AND gate with identical circuit count (3) and input configuration (3-input)
• Electrical Characteristics: Supply voltage range, output current ratings, input logic thresholds, and propagation delay must match exactly
• Physical Package: 14-DIP form factor with 0.300" (7.62mm) pitch for direct pin-compatible replacement
• Series Classification: 74F logic family designation
• Operating Temperature Range: 0°C to 70°C commercial grade

The SN74F11N from Texas Instruments meets all these criteria as a parametric equivalent, maintaining identical electrical performance and mechanical compatibility while offering active product status and improved availability.

Engineering Selection Recommendations

The SN74F11N represents a direct functional and mechanical replacement for the 74F11PC. Selection between these parts should be based on the following factors:

Product Status: The 74F11PC is obsolete, while the SN74F11N maintains active production status. For new designs or systems requiring long-term component availability, the SN74F11N is the appropriate choice.

Compliance & Certifications: The SN74F11N carries RoHS3 compliance certification, whereas the 74F11PC lists REACH Unaffected status. Both parts share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, indicating equivalent regulatory treatment.

Packaging Format: The 74F11PC is supplied in standard tube packaging, while the SN74F11N is also available in tube format. Both maintain identical 14-PDIP/14-MDIP physical specifications, ensuring direct socket compatibility.

Electrical Performance: All critical electrical parameters—supply voltage, output current, input thresholds, and propagation delay—are identical between the two parts, confirming functional interchangeability in existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the SN74F11N be used as a direct replacement for the 74F11PC in existing designs?

A: Yes. The SN74F11N is pin-compatible and electrically equivalent to the 74F11PC. All functional parameters, including logic operation, timing characteristics, and electrical ratings, are identical. Direct substitution in existing PCB layouts and circuit designs is supported.

Q: What is the primary reason for seeking a substitute for the 74F11PC?

A: The 74F11PC is classified as obsolete. The SN74F11N, produced by Texas Instruments, maintains active product status and ensures continued availability for replacement, repair, and new production requirements.

Q: Are there any differences in package dimensions between these parts?

A: No. Both the 74F11PC and SN74F11N use the 14-DIP package with 0.300" (7.62mm) pitch. Physical dimensions, pin spacing, and mounting characteristics are identical, enabling direct board-level substitution without layout modifications.

Q: Do these parts have different compliance or regulatory certifications?

A: The SN74F11N carries RoHS3 compliance, while the 74F11PC is REACH Unaffected. Both share identical ECCN and HTSUS classifications. Compliance requirements should be evaluated based on your specific application and regional regulations.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution is determined by matching logic type (3-channel AND gate with 3 inputs), supply voltage range (4.5V–5.5V), output current ratings (1mA high, 20mA low), input logic thresholds (0.8V low, 2V high), propagation delay (5.6ns @ 5V, 50pF), and operating temperature range (0°C–70°C).

Q: Is the SN74F11N available in the same packaging format as the 74F11PC?

A: Yes. The SN74F11N is available in tube packaging, matching the standard supply format of the 74F11PC. Both parts are supplied in quantities suitable for production and replacement applications.
