Substitute Part Grouping Explanation

Substitute parts for the MM74HC595N are classified based on functional and electrical equivalence within the 74HC logic family. The substitution criteria are determined by the following parameters:

  • Logic Type: Shift Register (1 element, 8-bit configuration)
  • Output Type: Tri-State
  • Function: Serial to Parallel, Serial conversion
  • Voltage Supply Range: 2V ~ 6V
  • Package: 16-DIP (0.300", 7.62mm)
  • Mounting: Through Hole

Parts meeting these criteria are electrically and mechanically compatible with the MM74HC595N. Variations in operating temperature range and product status do not affect functional substitution capability within the specified electrical parameters.

Engineering Selection Recommendations

The SN74HC595N (Texas Instruments) and CD74HC595E (Texas Instruments) are direct functional equivalents to the MM74HC595N. Both substitute parts maintain identical electrical specifications across voltage supply, logic function, output type, and package configuration.

The SN74HC595N provides equivalent operating temperature range (-40°C ~ 85°C) to the original MM74HC595N and carries active product status with ROHS3 compliance certification. This part is suitable for direct replacement in applications with standard temperature requirements.

The CD74HC595E extends the operating temperature range to -55°C ~ 125°C, providing broader thermal performance capability. This part is appropriate for applications requiring extended temperature operation and carries active product status with ROHS3 compliance certification.

Both substitute parts carry REACH Unaffected status and identical ECCN and HTSUS classifications as the original component, confirming regulatory equivalence.

Frequently Asked Questions (FAQ)

Q: Can the SN74HC595N directly replace the MM74HC595N in existing designs?

A: Yes. The SN74HC595N maintains identical electrical parameters including voltage supply range (2V ~ 6V), logic function (serial-to-parallel conversion), output type (tri-state), and 16-DIP package configuration. No circuit modifications are required.

Q: What is the difference between the SN74HC595N and CD74HC595E?

A: Both parts are functionally equivalent shift registers with identical core specifications. The primary difference is operating temperature range: SN74HC595N operates from -40°C to 85°C, while CD74HC595E operates from -55°C to 125°C. Select CD74HC595E for applications requiring extended temperature performance.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both SN74HC595N and CD74HC595E carry ROHS3 Compliant certification. The original MM74HC595N RoHS status was not specified in available documentation.

Q: Does package compatibility affect substitution?

A: No. All three parts use identical 16-DIP (0.300", 7.62mm) through-hole packaging. Pin-to-pin compatibility is maintained, allowing direct socket substitution.

Q: Why is the MM74HC595N listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured by onsemi. The SN74HC595N and CD74HC595E remain in active production, ensuring long-term supply availability and support.

Q: Can I use these parts interchangeably in high-temperature applications?

A: For applications exceeding -40°C to 85°C range, use the CD74HC595E, which supports -55°C to 125°C operation. The SN74HC595N maintains the original temperature specification and is suitable for standard industrial temperature ranges.
