Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74HCT367DB,112 is determined by the following critical parameters:

Logic function and architecture: Buffer, Non-Inverting with identical element and bit configuration (2 elements, 2 and 4 bits per element)

Output characteristics: 3-State output capability

Electrical specifications: Supply voltage range 4.5V ~ 5.5V, operating temperature -40°C ~ 125°C

Package compatibility: 16-SSOP surface mount package with identical physical dimensions (0.209", 5.30mm Width)

The SN74AHCT367DBR from Texas Instruments meets all substitution criteria. While the output current specification differs (8mA vs. 6mA for both high and low), this represents an enhancement in drive capability within the same logic family and does not compromise compatibility. Both parts maintain identical supply voltage ranges, operating temperature specifications, and physical packaging requirements.

Parameter Comparison

Engineering Selection Recommendations

The SN74AHCT367DBR is the direct functional equivalent for the obsolete 74HCT367DB,112. Both components maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring compatibility with current manufacturing and environmental standards. The Texas Instruments part is currently in active production status, providing supply continuity and long-term availability advantages over the obsolete Nexperia component. The enhanced output current specification (8mA vs. 6mA) of the SN74AHCT367DBR provides improved drive capability while maintaining full electrical and mechanical compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can the SN74AHCT367DBR directly replace the 74HCT367DB,112 in existing designs?

A: Yes. Both parts share identical logic function, element configuration, output type, supply voltage range, operating temperature range, and 16-SSOP package dimensions. Direct substitution is supported without circuit modification.

Q: What is the significance of the different output current ratings?

A: The SN74AHCT367DBR provides 8mA output current compared to the 74HCT367DB,112's 6mA. This represents increased drive capability and does not create compatibility issues. Circuits designed for 6mA operation will function correctly with the higher-current part.

Q: Are there packaging differences between these parts?

A: No. Both components use the 16-SSOP surface mount package with identical physical dimensions (0.209", 5.30mm Width). PCB footprints and assembly processes remain unchanged.

Q: Why is the 74HCT367DB,112 listed as obsolete?

A: The Nexperia part has reached end-of-life status. The SN74AHCT367DBR from Texas Instruments provides equivalent functionality with active production status, ensuring continued availability for new designs and system support.

Q: Do both parts meet current environmental and compliance standards?

A: Yes. Both the 74HCT367DB,112 and SN74AHCT367DBR are ROHS3 compliant with MSL rating of 1 (Unlimited), meeting current manufacturing and environmental requirements.
