Substitute Part Grouping Explanation

Substitution for the SN74LVC4245APWG4 is determined by strict alignment of the following critical parameters:

• Package compatibility: 24-TSSOP form factor with 0.173" width (4.40mm)
• Functional equivalence: Bidirectional voltage level translator with 1 circuit and 8 channels per circuit
• Output configuration: Tri-State output type
• Mounting method: Surface mount technology
• Compliance standards: ROHS3 compliance, MSL Level 1, REACH unaffected status
• Electrical classification: Logic category, 74LVC series base product number

Substitute parts must maintain identical package dimensions, pinout compatibility, and functional specifications to ensure direct replacement capability without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

SN74LVCC4245APW (Texas Instruments): This substitute maintains active product status with identical package specifications and functional parameters. It is ROHS3 compliant and MSL Level 1 rated. The operating temperature range matches the original part at -40°C to 85°C. This option provides direct compatibility for applications requiring Texas Instruments sourcing.

74LVC4245APW,118 (Nexperia USA Inc.): This substitute is manufactured by Nexperia and maintains the same 24-TSSOP package and bidirectional 8-channel translator configuration. It carries active product status with ROHS3 compliance and MSL Level 1 rating. The extended operating temperature range of -40°C to 125°C provides additional thermal margin for high-temperature applications. This option offers superior availability with 220,341 pieces in stock.

Both substitutes are electrically and mechanically compatible with the discontinued SN74LVC4245APWG4 for direct board-level replacement.

Frequently Asked Questions (FAQ)

Q: Can the SN74LVCC4245APW directly replace the SN74LVC4245APWG4?

A: Yes. Both parts share identical 24-TSSOP packaging, bidirectional 8-channel translator configuration, tri-state output type, and surface mount mounting method. Pinout and functional specifications are compatible for direct substitution.

Q: What is the difference between the two substitute options?

A: The primary differences are manufacturer (Texas Instruments vs. Nesperia) and operating temperature range. The Nexperia part (74LVC4245APW,118) supports -40°C to 125°C operation compared to -40°C to 85°C for the Texas Instruments SN74LVCC4245APW. Both maintain identical package dimensions and electrical functionality.

Q: Are both substitutes ROHS3 compliant?

A: Yes. Both SN74LVCC4245APW and 74LVC4245APW,118 are ROHS3 compliant with MSL Level 1 moisture sensitivity rating, matching the original part's compliance status.

Q: Does package compatibility guarantee functional compatibility?

A: Package compatibility combined with matching translator type, channel configuration, output type, and circuit count ensures functional compatibility. Both substitutes maintain these specifications identically to the original part.

Q: Which substitute offers better availability?

A: The 74LVC4245APW,118 from Nexperia offers significantly higher inventory availability at 220,341 pieces compared to 2,000 pieces for the SN74LVCC4245APW from Texas Instruments.
