Engineering Selection Recommendations

Primary Substitute: SN74HC367DR

The SN74HC367DR from Texas Instruments is the direct parametric equivalent with active product status. This part maintains identical electrical specifications and 16-SOIC packaging, with 3800 units currently in stock. Selection of this part preserves design continuity with the original manufacturer while ensuring ongoing availability.

Secondary Substitute: 74HC367D,653

The 74HC367D,653 from Nexperia USA Inc. provides functional equivalence with extended operating temperature range (-40°C ~ 125°C) and active product status. This part offers 8107 units in inventory and represents an alternative source for the 74HC367 logic buffer family. The expanded temperature specification provides additional operational margin for applications requiring extended thermal performance.

Tertiary Substitute: MC74HC367ADR2G

The MC74HC367ADR2G from onsemi maintains full electrical and mechanical compatibility with the original part. This device features the widest operating temperature range (-55°C ~ 125°C) and is available in Cut Tape and Digi-Reel packaging. Current product status is obsolete; however, 3365 units remain in stock. This part is suitable for applications where extended temperature performance is required and inventory availability is confirmed.

Frequently Asked Questions (FAQ)

Q: Can SN74HC367DR be used as a direct replacement for SN74HC367DT?

A: Yes. The SN74HC367DR is a parametric equivalent with identical logic type, element configuration, output type, current ratings, supply voltage range, and 16-SOIC package. Both parts operate within -40°C to 85°C and maintain ROHS3 compliance and MSL 1 rating. The primary difference is product status: SN74HC367DR is active while SN74HC367DT is discontinued.

Q: What is the difference between the 16-SOIC and 16-SO packages used in these parts?

A: Both designations refer to the same 16-pin Small Outline Integrated Circuit package with 0.154" (3.90mm) width. The 74HC367D,653 uses the 16-SO supplier device package designation while maintaining identical physical and electrical compatibility with the 16-SOIC specification.

Q: Are there temperature range differences that affect substitution?

A: The SN74HC367DT and SN74HC367DR both operate from -40°C to 85°C. The 74HC367D,653 extends to -40°C to 125°C, and the MC74HC367ADR2G extends to -55°C to 125°C. These extended ranges do not prevent substitution; they provide additional operational margin for applications requiring wider temperature performance.

Q: Do all substitute parts maintain RoHS3 compliance?

A: Yes. All identified substitute parts—SN74HC367DR, 74HC367D,653, and MC74HC367ADR2G—are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original SN74HC367DT specification.

Q: Which substitute part has the best current availability?

A: The 74HC367D,653 from Nexperia USA Inc. has the highest inventory level at 8107 units in stock, followed by SN74HC367DR at 3800 units and MC74HC367ADR2G at 3365 units.
