Substitute Part Grouping Explanation

Substitution of the 74F253PC is determined by strict equivalence across the following parameters:

• Circuit Configuration: 2 x 4:1 multiplexer topology
• Package Type: 16-DIP (0.300", 7.62mm) through-hole mounting
• Electrical Specifications: Voltage supply range 4.5V ~ 5.5V, output current ratings 3mA (high) and 24mA (low)
• Operating Temperature Range: 0°C ~ 70°C
• Series Classification: 74F logic family

The SN74F253N from Texas Instruments meets all specified parameters and is classified as an active product, providing a direct functional replacement for the obsolete 74F253PC.

Parameter Comparison

Engineering Selection Recommendations

The SN74F253N is the direct equivalent for the 74F253PC. Both components share identical electrical and mechanical specifications within the 74F logic family. The primary distinction is product status: the 74F253PC is obsolete, while the SN74F253N maintains active production status from Texas Instruments.

For new designs or system maintenance requiring the 74F253 multiplexer function, the SN74F253N is the appropriate selection. Both parts comply with REACH regulations and carry EAR99 ECCN classification. The SN74F253N is RoHS3 compliant, supporting modern supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can the SN74F253N directly replace the 74F253PC in existing circuits?

A: Yes. Both components are electrically and mechanically identical across all specified parameters: 2 x 4:1 multiplexer configuration, 16-DIP through-hole package, 4.5V ~ 5.5V supply voltage, and 0°C ~ 70°C operating temperature range. Pin-for-pin compatibility is maintained.

Q: What is the difference between the 74F253PC and SN74F253N?

A: The components are functionally equivalent. The 74F253PC (onsemi) is obsolete, while the SN74F253N (Texas Instruments) is in active production. The SN74F253N includes RoHS3 compliance certification.

Q: Are there packaging differences between these parts?

A: Both parts use the 16-DIP (0.300", 7.62mm) through-hole package. The 74F253PC is supplied in standard packaging, while the SN74F253N is available in tube packaging. Both are suitable for through-hole PCB assembly.

Q: What compliance certifications apply to these parts?

A: Both the 74F253PC and SN74F253N are REACH unaffected and carry EAR99 ECCN classification. The SN74F253N additionally meets RoHS3 compliance requirements.

Q: Can I use these parts in new product designs?

A: The SN74F253N is recommended for new designs due to its active product status and RoHS3 compliance. The 74F253PC, being obsolete, is suitable only for legacy system maintenance or repair applications.
