Key Parameters

Substitute Part Grouping Explanation

Substitution of the N74F245DB,112 is determined by strict equivalence across the following critical parameters:

• Logic type and function: Non-inverting transceiver with identical element and bit configuration
• Electrical specifications: Matching output current ratings, supply voltage range, and operating temperature
• Package specification: Identical 20-SSOP surface mount package with matching physical dimensions
• Compliance certifications: ROHS3 compliance and MSL rating consistency

The substitute part SN74F245DBR meets all these criteria, providing functional and electrical equivalence while offering improved supply availability through active product status.

Parameter Comparison

Engineering Selection Recommendations

The SN74F245DBR manufactured by Texas Instruments is a direct functional equivalent to the N74F245DB,112. Both components share identical electrical characteristics, package specifications, and compliance certifications.

The primary distinction is product status: the N74F245DB,112 is obsolete, while the SN74F245DBR maintains active status with significantly higher inventory availability (3256 units versus 871 units). For new designs or ongoing production requiring this transceiver function, the SN74F245DBR is the appropriate selection based on supply chain continuity and long-term availability.

Both parts satisfy ROHS3 compliance and MSL Level 1 requirements, ensuring compatibility with modern manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can the SN74F245DBR directly replace the N74F245DB,112 in existing designs?

A: Yes. The SN74F245DBR is electrically and mechanically equivalent. Both components feature identical output current ratings, supply voltage specifications, operating temperature range, and 20-SSOP package dimensions. No circuit modifications are required.

Q: What is the significance of the product status difference?

A: The N74F245DB,112 is classified as obsolete, indicating NXP has discontinued production. The SN74F245DBR maintains active status, ensuring continued manufacturing and availability from Texas Instruments. For production continuity, the active part is preferred.

Q: Are there packaging differences between these parts?

A: No. Both the N74F245DB,112 and SN74F245DBR use the 20-SSOP surface mount package with identical physical dimensions (0.209" width, 5.30mm). They are compatible with the same PCB footprints and assembly processes.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity ratings, meeting current environmental and reliability requirements.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution is based on matching logic type (non-inverting transceiver), element configuration (1 element, 8 bits per element), output type (3-state), output current specifications (3mA/24mA and 15mA/64mA), supply voltage range (4.5V–5.5V), and operating temperature (0°C–70°C).
