Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74LVC240APW/AUJ are identified based on strict parametric equivalence across the following critical criteria:

• Logic function: Buffer, Inverting configuration with identical element and bit-per-element count
• Electrical performance: Matching output current ratings (24mA high/low), supply voltage range (1.2V ~ 3.6V), and operating temperature range (-40°C ~ 125°C)
• Package specification: 20-TSSOP form factor with identical physical dimensions (0.173", 4.40mm width)
• Mounting technology: Surface mount compatibility
• Compliance: ROHS3 compliance and MSL rating of 1

Substitutes may differ in packaging configuration (bulk vs. tape/reel), supplier designation, or inventory source while maintaining full electrical and mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both the 74LVC240APW/AUJ and 74LVC240APW,118 are active production parts from NXP with full ROHS3 compliance and identical electrical specifications. Selection between these parts should be based on:

• Packaging requirement: The 74LVC240APW/AUJ is supplied in tape/reel configuration, while the 74LVC240APW,118 is supplied in bulk packaging
• Inventory availability: The 74LVC240APW,118 offers significantly higher stock levels (42885 units vs. 754 units)
• Supply chain considerations: Both parts maintain the same MSL rating of 1 (unlimited moisture sensitivity level), eliminating storage and handling differentiation

For applications requiring immediate availability or high-volume procurement, the 74LVC240APW,118 provides superior inventory access without electrical or mechanical compromise.

Frequently Asked Questions (FAQ)

Q: Are the 74LVC240APW/AUJ and 74LVC240APW,118 pin-for-pin compatible?

A: Yes. Both parts use the identical 20-TSSOP package with matching pinout, electrical characteristics, and functional behavior. They are direct substitutes at the circuit board level.

Q: What is the difference between tape/reel and bulk packaging?

A: Tape/reel packaging (74LVC240APW/AUJ) is configured for automated pick-and-place assembly equipment, while bulk packaging (74LVC240APW,118) is supplied in loose component form. The electrical and mechanical specifications are identical; packaging choice depends on assembly process requirements.

Q: Can I use the 74LVC240APW,118 in place of the 74LVC240APW/AUJ in my design?

A: Yes, provided your assembly process can accommodate bulk packaging. The parts are electrically and mechanically equivalent with no design modifications required.

Q: Are both parts RoHS compliant?

A: Yes. Both the 74LVC240APW/AUJ and 74LVC240APW,118 are ROHS3 compliant and suitable for applications requiring lead-free component specifications.

Q: What is the MSL rating, and does it differ between these parts?

A: Both parts carry an MSL rating of 1 (unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage practices apply equally to both variants.

Q: What supply voltage range do these parts support?

A: Both parts operate across a supply voltage range of 1.2V to 3.6V, making them suitable for low-voltage logic applications and mixed-signal systems.
