Substitute Part Grouping Explanation

Substitution for the SN74HC368DT is determined by strict equivalence across the following critical parameters:

• Logic Type: Buffer, Inverting
• Number of Elements: 2
• Number of Bits per Element: 2, 4 (Hex)
• Output Type: 3-State
• Current - Output High, Low: 7.8mA, 7.8mA
• Voltage - Supply: 2V ~ 6V
• Package / Case: 16-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All substitute parts listed maintain these core electrical and mechanical specifications, ensuring functional and physical compatibility within the 74HC368 series logic buffer family.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the obsolete SN74HC368DT, the following selection criteria apply:

Parametric Equivalent (SN74HC368DR): This Texas Instruments part maintains identical electrical specifications and package configuration as the main part. With Active product status, it provides direct continuity for new procurement and design refresh cycles. Tape & Reel packaging supports high-volume manufacturing environments.

Direct Manufacturer Alternative (MC74HC368ADR2G): The onsemi equivalent offers extended operating temperature range (-55°C to 125°C) compared to the original specification (-40°C to 85°C), providing broader environmental coverage for demanding applications. Product status is Obsolete; however, it maintains full electrical and mechanical compatibility. Cut Tape packaging suits lower-volume or prototype applications.

Upgrade Option (74HC368D,653): The Nexperia part is currently Active and offers extended upper operating temperature limit (-40°C to 125°C), supporting applications requiring higher temperature performance. Tape & Reel packaging aligns with production-scale requirements.

All substitute parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring regulatory and moisture handling consistency with the original part.

Frequently Asked Questions (FAQ)

Q: Can SN74HC368DR be used as a direct replacement for SN74HC368DT?

A: Yes. Both parts share identical electrical specifications (logic type, element count, bit configuration, output type, current ratings, supply voltage, and operating temperature range) and package configuration (16-SOIC surface mount). The primary difference is product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. Tube).

Q: What is the difference between the operating temperature ranges of these substitutes?

A: The SN74HC368DT and SN74HC368DR operate from -40°C to 85°C. The MC74HC368ADR2G extends to -55°C to 125°C, and the 74HC368D,653 extends to -40°C to 125°C. Applications requiring operation beyond -40°C to 85°C should select parts with extended temperature ratings.

Q: Are all substitute parts in the same package?

A: All substitute parts use the 16-SOIC (0.154", 3.90mm Width) package, ensuring physical compatibility on existing PCBs. Packaging format (Tube, Tape & Reel, or Cut Tape) differs but does not affect electrical or mechanical fit.

Q: Do all parts meet the same compliance standards?

A: Yes. All parts listed are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), maintaining regulatory and handling consistency with the original SN74HC368DT.

Q: Which substitute should be selected for new designs?

A: For new designs, SN74HC368DR (Active status, Texas Instruments) or 74HC368D,653 (Active status, Nexperia) are preferred due to their Active product status, ensuring long-term availability and supply chain stability.
