Substitute Part Grouping Explanation

Substitution for the SN74LS14NE4 is determined by strict equivalence across the following critical parameters:

• Base product number: 74LS14
• Logic type and circuit configuration: 6-channel inverter with Schmitt trigger
• Electrical specifications: Supply voltage 4.75V ~ 5.25V, output current ratings, input logic levels, and propagation delay
• Package type: 14-DIP through-hole mounting
• Compliance certifications: ROHS3 compliance and REACH unaffected status

The SN74LS14N qualifies as a direct substitute based on identical electrical and mechanical specifications. The primary distinction is packaging format and product status availability.

Parameter Comparison

Engineering Selection Recommendations

The SN74LS14N is the direct substitute for the SN74LS14NE4. Both components meet ROHS3 compliance requirements and maintain identical electrical and mechanical specifications. The SN74LS14N carries active product status with significantly higher inventory availability (16,094 units in stock versus 775 units for the original part), making it the preferred selection for new designs and production continuity. Both parts are suitable for applications requiring 6-channel inverter logic with Schmitt trigger input conditioning in 5V TTL systems.

Frequently Asked Questions (FAQ)

Q: Can the SN74LS14N directly replace the SN74LS14NE4 in existing designs?

A: Yes. Both parts share identical electrical specifications, operating parameters, and 14-DIP package dimensions. No circuit modifications are required.

Q: What is the difference between SN74LS14NE4 and SN74LS14N?

A: The primary difference is packaging format. The SN74LS14NE4 uses a specific packaging designation (NE4), while the SN74LS14N uses standard tube packaging. Electrical performance and pin configuration are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both the SN74LS14NE4 and SN74LS14N are ROHS3 compliant and REACH unaffected.

Q: What supply voltage range is required for these inverter ICs?

A: Both parts operate within a supply voltage range of 4.75V to 5.25V, standard for TTL logic families.

Q: What is the propagation delay specification?

A: Maximum propagation delay is 22 nanoseconds at 5V with a 15pF load for both parts.

Q: Are these parts suitable for new production designs?

A: The SN74LS14N is recommended for new designs due to its active product status and higher inventory availability. The SN74LS14NE4 is discontinued and should be replaced with the SN74LS14N for ongoing production.
