Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74LVC623AD,118 is determined by strict alignment across the following critical parameters:

Core Functional Parameters:

• Logic Type: Transceiver, Non-Inverting
• Number of Elements: 1
• Number of Bits per Element: 8
• Output Type: 3-State
• Current - Output High, Low: 24mA, 24mA
• Operating Temperature: -40°C ~ 125°C (TA)

Electrical Compatibility Parameters:

• Voltage - Supply: 1.2V ~ 3.6V (minimum requirement)
• Package / Case: 20-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts must match all core functional parameters and maintain electrical compatibility within the specified voltage and temperature ranges. Package and mounting type must be identical to ensure direct PCB compatibility.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain full functional and electrical equivalence to the 74LVC623AD,118 across core parameters. Selection should be based on product availability, supply chain status, and application-specific requirements.

For Standard Industrial Applications: 74LVC245AD,118 (Nexperia USA Inc.) is the primary parametric equivalent. This part is actively manufactured and maintains identical electrical specifications including the 1.2V to 3.6V supply voltage range. It is ROHS3 compliant and carries MSL 1 rating.

For Automotive Applications: 74LVC245AD-Q100J or 74LVCH245AD-Q100J are suitable when AEC-Q100 automotive qualification is required. Both parts maintain full functional equivalence and are actively produced.

For Texas Instruments Supply Chain: SN74LVC245ADW (Texas Instruments) provides functional equivalence with the constraint of a 1.65V minimum supply voltage. This part is suitable for applications where the system supply voltage remains above 1.65V.

For 74LVCH Series Compatibility: 74LVCH245AD,118 and 74LVCH245AD-Q100J offer equivalent functionality within the 74LVCH series. These parts are actively manufactured and maintain all critical electrical parameters.

Frequently Asked Questions (FAQ)

Q: Can the 74LVC623AD,118 be directly replaced with any of the listed substitutes?

A: Yes, all listed substitute parts are direct functional replacements. They maintain identical logic type, bit width, output configuration, current ratings, and operating temperature range. PCB layout compatibility is ensured through identical 20-SOIC packaging.

Q: What is the key difference between SN74LVC245ADW and other substitutes?

A: SN74LVC245ADW has a minimum supply voltage of 1.65V, compared to 1.2V for other substitutes. This part is suitable only for applications where the system supply voltage remains at or above 1.65V throughout operation.

Q: Are automotive-grade parts (AEC-Q100) required for this application?

A: Automotive qualification is not inherent to the 74LVC623AD,118. Use automotive-grade substitutes (74LVC245AD-Q100J or 74LVCH245AD-Q100J) only if your application or customer requirements explicitly mandate AEC-Q100 compliance.

Q: What is the difference between 74LVC and 74LVCH series substitutes?

A: Both series maintain identical functional and electrical specifications for this application. The 74LVCH series represents an enhanced variant within the same logic family. Selection between them should be based on availability and supply chain preference.

Q: Are all substitutes ROHS3 compliant?

A: Yes, all listed substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's compliance profile.

Q: Can I use these substitutes in new designs?

A: Yes. All substitute parts carry active product status, ensuring long-term availability and manufacturing support. They are suitable for both legacy system maintenance and new design implementations.
