Substitute Part Grouping Explanation

Substitution of the SN74HC368DBRE4 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
• Operating Temperature: -40°C ~ 85°C (TA)
• Series: 74HC
• Base Product Number: 74HC368
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The SN74HC368PWR qualifies as a direct substitute based on identical electrical specifications and functional characteristics. The primary difference is the package format: the substitute uses 16-TSSOP (0.173", 4.40mm Width) instead of 16-SSOP (0.209", 5.30mm Width). Both packages are surface-mount configurations with compatible pinout and electrical performance.

Parameter Comparison

Engineering Selection Recommendations

The SN74HC368PWR is the manufacturer-recommended substitute for the obsolete SN74HC368DBRE4. Both parts maintain identical electrical specifications, functional characteristics, and compliance certifications (ROHS3 Compliant, MSL Level 1).

The SN74HC368PWR carries Active product status, ensuring ongoing availability and supply chain support. The package transition from 16-SSOP to 16-TSSOP represents a standard industry evolution toward smaller form factors while maintaining pinout compatibility and electrical performance.

Selection of the SN74HC368PWR is appropriate for new designs, production continuity, and replacement applications where the obsolete SN74HC368DBRE4 is no longer available.

Frequently Asked Questions (FAQ)

Q: Are the SN74HC368DBRE4 and SN74HC368PWR electrically identical?

A: Yes. Both parts share identical electrical specifications including logic type, output characteristics, supply voltage range, operating temperature, and output current ratings.

Q: What is the difference between the 16-SSOP and 16-TSSOP packages?

A: The 16-SSOP package measures 0.209" (5.30mm) in width, while the 16-TSSOP package measures 0.173" (4.40mm) in width. Both are surface-mount packages with compatible pinout. The TSSOP represents a more compact form factor.

Q: Can I use the SN74HC368PWR as a direct replacement on existing PCBs designed for the SN74HC368DBRE4?

A: PCB layout compatibility depends on the specific footprint design. While both packages are surface-mount with the same pinout, the dimensional differences require verification of the PCB footprint. Consult the device datasheets for detailed package dimensions and land pattern specifications.

Q: Why is the SN74HC368DBRE4 classified as Obsolete?

A: The SN74HC368DBRE4 has reached end-of-life status. The SN74HC368PWR, with its Active product status, represents the current manufacturing offering from Texas Instruments for this logic function.

Q: Are both parts RoHS compliant?

A: Yes. Both the SN74HC368DBRE4 and SN74HC368PWR are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited).
