Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74HC365N,652 are qualified based on the following critical parameters:

• Logic function: Buffer, Non-Inverting with identical element and bit configuration
• Output characteristics: 3-State output with matching current specifications (7.8mA high and low)
• Supply voltage range: 2V ~ 6V compatibility
• Package format: 16-DIP through-hole mounting
• Base product series: 74HC365 family

The substitute parts CD74HC365E and SN74HC365N meet these core electrical and mechanical requirements, enabling direct functional replacement in applications where the 74HC365N,652 is specified.

Parameter Comparison

Engineering Selection Recommendations

SN74HC365N (Texas Instruments) is the primary substitute for new designs and ongoing applications. This part maintains ROHS3 compliance matching the original 74HC365N,652, carries active product status ensuring long-term availability, and provides identical electrical specifications. The operating temperature range of -40°C ~ 85°C covers standard industrial applications, though it is narrower than the original specification.

CD74HC365E (Harris Corporation) provides functional equivalence with extended operating temperature range (-55°C ~ 125°C), suitable for extreme temperature environments. However, this part is obsolete and carries RoHS non-compliance status, limiting its use to legacy system maintenance where regulatory requirements do not apply.

For applications requiring the full -40°C ~ 125°C operating range with current product availability and compliance certification, SN74HC365N is the recommended selection.

Frequently Asked Questions (FAQ)

Q: Can CD74HC365E and SN74HC365N be used interchangeably with 74HC365N,652?

A: Both parts share identical logic function, output characteristics, supply voltage range, and 16-DIP package format. Functional substitution is valid. Temperature range differences must be evaluated against application requirements.

Q: What is the significance of the operating temperature range differences?

A: The 74HC365N,652 and CD74HC365E support -40°C ~ 125°C operation, while SN74HC365N operates from -40°C ~ 85°C. Applications requiring operation above 85°C must use CD74HC365E or the original part. Standard industrial applications typically operate within the SN74HC365N range.

Q: Why is RoHS compliance status different across substitutes?

A: RoHS compliance reflects manufacturing date and process standards. ROHS3-compliant parts (74HC365N,652 and SN74HC365N) meet current environmental regulations. CD74HC365E predates these requirements. Regulatory requirements for the end application determine which parts are acceptable.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use 16-DIP (0.300", 7.62mm) through-hole packaging with identical pinout, enabling direct socket replacement without PCB modification.

Q: What is the current availability status of these parts?

A: SN74HC365N carries active product status with 2000 units in stock. CD74HC365E and 74HC365N,652 are obsolete with limited inventory (1400 and 865 units respectively). For new procurement, SN74HC365N is the recommended choice.
