Substitute Part Grouping Explanation

Substitution eligibility for the 74HC368D,652 is determined by strict equivalence across the following critical parameters:

Logic Type: Buffer, Inverting (mandatory match)
Number of Elements: 2 (mandatory match)
Number of Bits per Element: 2, 4 (Hex) (mandatory match)
Output Type: 3-State (mandatory match)
Current - Output High, Low: 7.8mA, 7.8mA (mandatory match)
Voltage - Supply: 2V ~ 6V (mandatory match)
Package / Case: 16-SOIC (0.154", 3.90mm Width) (mandatory match)
Mounting Type: Surface Mount (mandatory match)

All identified substitute parts maintain these core electrical and mechanical specifications. Variations in operating temperature range, product status, and RoHS compliance are noted but do not preclude functional substitution when application requirements permit.

Engineering Selection Recommendations

Primary Recommendation: SN74HC368DR (Texas Instruments)

The SN74HC368DR is the preferred substitute. It maintains full electrical and mechanical equivalence to the 74HC368D,652, carries Active product status ensuring long-term availability, holds ROHS3 compliance, and is supplied in Tape & Reel packaging suitable for automated assembly. This part provides the highest procurement reliability and supply chain continuity.

Secondary Recommendation: SN74HC368NSR (Texas Instruments)

The SN74HC368NSR offers identical electrical specifications and Active product status. It is supplied in Cut Tape & Digi-Reel packaging. Note the package width specification of 0.209" (5.30mm) versus the primary part's 0.154" (3.90mm). Verify PCB footprint compatibility before selection.

Alternative: MC74HC368ADR2G (onsemi)

The MC74HC368ADR2G provides full functional equivalence with extended lower operating temperature range (-55°C versus -40°C). It maintains ROHS3 compliance and Obsolete product status. This option is suitable when extended temperature performance is required.

Not Recommended: CD74HC368M (Harris Corporation)

While electrically equivalent, this part carries RoHS non-compliance status, limiting its applicability in regulated environments and modern supply chains.

Frequently Asked Questions (FAQ)

Q: Can SN74HC368NSR be used as a direct replacement for 74HC368D,652?

A: Electrical substitution is valid. However, the SN74HC368NSR package width differs (0.209" versus 0.154"). Verify that your PCB footprint accommodates this dimensional variation before implementation.

Q: What is the primary advantage of selecting SN74HC368DR over other substitutes?

A: The SN74HC368DR combines full electrical equivalence, Active product status for assured long-term availability, ROHS3 compliance, and standard Tape & Reel packaging optimized for production environments.

Q: Are there temperature range limitations when substituting with SN74HC368D or SN74HC368DR?

A: Both parts operate across -40°C to 85°C, which is narrower than the original 74HC368D,652 range of -40°C to 125°C. Applications requiring operation above 85°C require alternative selections such as MC74HC368ADR2G or CD74HC368MT.

Q: Does RoHS compliance affect substitution decisions?

A: RoHS3 compliance is standard across most active substitutes. CD74HC368M is RoHS non-compliant and should be avoided in applications subject to RoHS regulations or customer requirements.

Q: What packaging options are available?

A: SN74HC368DR is supplied in Tape & Reel (TR). SN74HC368NSR is supplied in Cut Tape (CT) & Digi-Reel. MC74HC368ADR2G is supplied in Cut Tape (CT). Select based on assembly process requirements.
