Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74LVC623AD,112 is determined by strict alignment of the following critical parameters:

• Logic Type: Transceiver, Non-Inverting
• Number of Elements: 1
• Number of Bits per Element: 8
• Output Type: 3-State
• Output Current Capability: 24mA (High and Low)
• Package / Case: 20-SOIC (0.295", 7.50mm Width)
• Operating Temperature Range: -40°C ~ 125°C (TA)
• RoHS Compliance: ROHS3 Compliant

The SN74LVC245ADW from Texas Instruments meets all substitution criteria. While the supply voltage range differs (1.65V ~ 3.6V versus 1.2V ~ 3.6V), the substitute part maintains functional compatibility within the overlapping voltage specification of 1.65V to 3.6V. The substitute part is currently in active production status, ensuring availability and long-term support.

Parameter Comparison

Engineering Selection Recommendations

The SN74LVC245ADW is the qualified substitute for the 74LVC623AD,112. Selection of this alternative is supported by the following factors:

• All functional and electrical parameters align with the original specification within the overlapping supply voltage range of 1.65V to 3.6V
• The substitute part maintains identical package geometry and pinout compatibility
• Both parts carry ROHS3 compliance and identical moisture sensitivity ratings
• The substitute part is in active production status, ensuring long-term availability and supply chain stability
• The substitute part is manufactured by Texas Instruments, a primary logic IC supplier with established quality and reliability standards

Frequently Asked Questions (FAQ)

Q: Can the SN74LVC245ADW be used as a direct replacement for the 74LVC623AD,112?

A: Yes, within the overlapping supply voltage range of 1.65V to 3.6V. If your system operates at voltages below 1.65V, the substitute part is not suitable. Verify your system's supply voltage specification before implementation.

Q: What is the primary difference between these two parts?

A: The supply voltage range differs. The original part operates from 1.2V to 3.6V, while the substitute operates from 1.65V to 3.6V. All other electrical and functional parameters are identical.

Q: Are the packages physically identical?

A: Yes. Both parts use the 20-SOIC package with identical dimensions (0.295", 7.50mm Width) and pinout configuration, enabling direct PCB-level substitution.

Q: Why is the original part listed as obsolete?

A: The 74LVC623AD,112 has been discontinued by NXP Semiconductors. The SN74LVC245ADW remains in active production and is the recommended alternative for new designs and ongoing system support.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical RoHS3 compliance status and moisture sensitivity level (MSL 1 - Unlimited), ensuring equivalent environmental and regulatory compliance.
