Substitute Part Grouping Explanation

Substitute parts for the 74LVC623APW,112 are identified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

• Logic type: Non-inverting transceiver configuration
• Bit width: 8 bits per element
• Output configuration: 3-state output
• Output current capability: 24mA high and low
• Supply voltage range: Minimum 1.2V to 3.6V maximum
• Package type: 20-TSSOP surface mount
• Operating temperature range: -40°C to 125°C
• RoHS and MSL compliance: ROHS3 Compliant, MSL 1

Parts meeting all these parameters are classified as direct substitutes. Parts with overlapping but not identical voltage ranges or different product status are classified as parametric equivalents.

Parameter Comparison

Engineering Selection Recommendations

SN74LVC245APWR (Texas Instruments) is the preferred direct substitute for the 74LVC623APW,112. This part maintains all critical electrical parameters including 24mA output current, 3-state output configuration, and 20-TSSOP package geometry. The primary advantage is active product status with 45,300 units in stock, ensuring long-term availability and supply chain continuity. The minimum supply voltage specification of 1.65V is higher than the original 1.2V minimum, which is acceptable for applications operating above 1.65V. ROHS3 compliance and MSL 1 rating match the original specification.

74LVC245APW,112 (Nexperia USA Inc.) serves as a parametric equivalent with identical electrical specifications to the original part, including the 1.2V minimum supply voltage. However, this part shares obsolete product status with the original, limiting its suitability for new designs or long-term procurement strategies. It is suitable for legacy system maintenance where the 1.2V minimum voltage requirement is critical.

Frequently Asked Questions (FAQ)

Q: Can SN74LVC245APWR replace 74LVC623APW,112 in all applications?

A: SN74LVC245APWR is electrically compatible for applications where the supply voltage remains at or above 1.65V. The original part specifies a 1.2V minimum, so designs operating between 1.2V and 1.65V require the 74LVC245APW,112 (Nexperia) or continued use of the original NXP part.

Q: What is the difference between the NXP and Nexperia versions?

A: Both the 74LVC623APW,112 (NXP) and 74LVC245APW,112 (Nexperia) share identical electrical specifications and 20-TSSOP packaging. The primary difference is manufacturer identity and product status. Nexperia is the spin-off semiconductor division from NXP, and both parts are classified as obsolete.

Q: Why is the Texas Instruments part recommended despite the higher minimum voltage?

A: The SN74LVC245APWR offers active product status with substantial inventory availability (45,300 units), ensuring reliable procurement for current and future applications. The 1.65V minimum voltage specification accommodates the majority of modern 3.3V and lower voltage logic systems. Applications strictly requiring 1.2V operation should specify the Nexperia equivalent.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 20-TSSOP package with identical pinout, enabling direct PCB-level substitution without layout modifications.

Q: What compliance certifications apply to these substitutes?

A: All three parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and reliability standards for industrial and commercial applications.
