SN74HC365D Equivalent & Substitute Parts
Part Overview
The SN74HC365D is a non-inverting buffer logic IC manufactured by Texas Instruments, featuring 1 element with 6 bits per element and 3-state output capability. This 16-SOIC surface mount device operates across a 2V to 6V supply voltage range and is designed for general-purpose buffering applications in digital logic circuits.
The SN74HC365D is currently discontinued at DiGi Electronics. Equivalent and substitute parts are available from active product lines, making substitution necessary for new designs and ongoing production requirements.

Substitute Part Grouping Explanation
Substitution of the SN74HC365D is determined by strict equivalence across the following critical parameters:
- Logic Type: Buffer, Non-Inverting
- Number of Elements: 1
- Number of Bits per Element: 6
- Output Type: 3-State
- Output Current Capability: 7.8mA (High and Low)
- Supply Voltage Range: 2V ~ 6V
- Package / Case: 16-SOIC form factor
- Mounting Type: Surface Mount
- RoHS Compliance: ROHS3 Compliant
Substitute parts must maintain identical electrical specifications and physical package dimensions to ensure direct replacement without circuit redesign. Operating temperature range and product status may vary between substitutes based on manufacturer specifications and application requirements.

Engineering Selection Recommendations
For new designs and production applications, SN74HC365DR (Texas Instruments, Active status) provides direct electrical and mechanical compatibility with the discontinued SN74HC365D while maintaining current manufacturer support and availability.
The Nexperia USA Inc. variants (74HC365D,653 and 74HC365D-Q100,118) offer extended operating temperature range (-40°C ~ 125°C) compared to the original specification (-40°C ~ 85°C), providing enhanced thermal performance for demanding environments. The 74HC365D-Q100,118 variant includes AEC-Q100 automotive qualification for applications requiring automotive-grade components.
The onsemi MC74HC365ADR2G (Active status) provides the widest operating temperature range (-55°C ~ 125°C) and is suitable for extreme temperature applications. The MC74HC365ADG variant is obsolete and should be avoided for new designs.
All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and identical electrical output characteristics (7.8mA output current capability and 2V ~ 6V supply voltage range).
Frequently Asked Questions (FAQ)
Q: Can SN74HC365DR be used as a direct replacement for SN74HC365D?
A: Yes. SN74HC365DR is electrically and mechanically identical to SN74HC365D. Both devices feature identical logic type, element count, bit configuration, output type, output current capability, and supply voltage range. SN74HC365DR is currently in active production status.
Q: What is the difference between the Nexperia and onsemi substitute options?
A: All substitute parts maintain identical electrical specifications and 16-SOIC package form factor. The primary differences are operating temperature range and product status. Nexperia variants support -40°C ~ 125°C operation, while onsemi variants support -55°C ~ 125°C operation. The 74HC365D-Q100,118 includes AEC-Q100 automotive qualification.
Q: Is the 74HC365D,653 suitable for automotive applications?
A: The 74HC365D,653 is not automotive-qualified. For automotive applications requiring AEC-Q100 certification, use the 74HC365D-Q100,118 variant from Nexperia USA Inc.
Q: Can I use MC74HC365ADG as a substitute?
A: MC74HC365ADG is obsolete and should not be selected for new designs. Use active alternatives such as SN74HC365DR, 74HC365D,653, 74HC365D-Q100,118, or MC74HC365ADR2G instead.
Q: Are all substitute parts RoHS compliant?
A: Yes. All listed substitute parts are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity rating, matching the original SN74HC365D specifications.
Q: What packaging options are available for substitutes?
A: All substitute parts are supplied in 16-SOIC surface mount package form factor. Packaging configurations vary by supplier: SN74HC365DR is available in Cut Tape and Digi-Reel formats; Nexperia and onsemi variants are supplied in Tape & Reel format.
