Substitute Part Grouping Explanation

Substitution for the 74LVC623APW-Q100J is determined by strict equivalence across the following critical 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
• Voltage - Supply: 1.2V ~ 3.6V (minimum requirement)
• Operating Temperature: -40°C ~ 125°C (TA)
• Package / Case: 20-TSSOP (0.173", 4.40mm Width)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts are grouped into two categories: parametric equivalents from active product lines and direct manufacturer alternatives. All listed substitutes maintain identical electrical specifications and package dimensions, ensuring pin-for-pin compatibility and functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring direct replacement of the obsolete 74LVC623APW-Q100J, the following selection criteria apply:

Automotive-Grade Applications (AEC-Q100 Required):

• 74LVC245APW-Q100J (Nexperia USA Inc.) — Active product status with automotive qualification and AEC-Q100 certification. Maintains identical electrical specifications and supply voltage range of 1.2V ~ 3.6V.
• 74LVCH245APW-Q100J (Nexperia USA Inc.) — Active product status with automotive qualification and AEC-Q100 certification. Functionally equivalent with identical electrical performance.

General Industrial Applications (Non-Automotive):

• 74LVC245APW,118 (NXP Semiconductors) — Active product with highest inventory availability (190,454 pcs). Maintains all critical electrical parameters and 1.2V ~ 3.6V supply voltage range.
• SN74LVC245APWR (Texas Instruments) — Active product with extensive inventory (45,300 pcs). Note: Supply voltage range is 1.65V ~ 3.6V, which is narrower than the original specification. Suitable only for applications operating above 1.65V.
• 74LVC245APW/AUJ (NXP USA Inc.) — Active product with parametric equivalence across all critical parameters.
• 74LVCH245APW/AUJ (NXP USA Inc.) — Active product with parametric equivalence across all critical parameters.
• 74LVCH245APW,118 (NXP Semiconductors) — Active product with highest inventory availability (257,577 pcs) among 74LVCH series variants.

All listed substitutes are ROHS3 compliant and maintain MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage processes.

Frequently Asked Questions (FAQ)

Q: Can the 74LVC245APW,118 directly replace the 74LVC623APW-Q100J? A: Yes. Both parts share identical logic type (Transceiver, Non-Inverting), 8-bit configuration, 3-state output, 24mA output current, 1.2V ~ 3.6V supply voltage range, -40°C ~ 125°C operating temperature, and 20-TSSOP package. The 74LVC245APW,118 is pin-for-pin compatible and functionally equivalent.

Q: What is the difference between 74LVC and 74LVCH series parts? A: Both series maintain identical electrical specifications for the parameters listed: logic type, bit configuration, output type, current ratings, supply voltage, operating temperature, and package. The primary distinction is series designation; both are functionally interchangeable for this application.

Q: Why does the SN74LVC245APWR have a different supply voltage range? A: The SN74LVC245APWR (Texas Instruments) specifies a supply voltage range of 1.65V ~ 3.6V, compared to 1.2V ~ 3.6V for other substitutes. This part is suitable only for applications where the minimum supply voltage is 1.65V or higher. For designs requiring operation below 1.65V, select alternative substitutes with the 1.2V ~ 3.6V range.

Q: Are automotive-grade substitutes required for all applications? A: Automotive-grade substitutes (74LVC245APW-Q100J and 74LVCH245APW-Q100J) with AEC-Q100 qualification are required only for automotive applications. General industrial applications may use non-automotive-grade equivalents. Verify application requirements before selection.

Q: What is the significance of the Q100J suffix? A: The Q100J suffix indicates AEC-Q100 automotive qualification. Parts bearing this suffix meet automotive industry reliability and qualification standards. For automotive applications, select only parts with this designation.

Q: Are all substitutes ROHS3 compliant? A: All listed substitutes are ROHS3 compliant except 74LVCH245APW,118, for which RoHS status is not specified in the provided data. Verify RoHS compliance with the manufacturer if required for your application.

Q: What packaging options are available? A: All substitutes are supplied in 20-TSSOP surface mount package (0.173", 4.40mm Width). Packaging variants (Tape & Reel, Bulk, Cut Tape) differ by supplier but do not affect electrical or mechanical compatibility.
