Parameter Comparison

Engineering Selection Recommendations

SN74HC368N (Texas Instruments) is the primary recommended substitute. This part maintains Active product status, ensuring long-term availability and manufacturing support. It is ROHS3 compliant and provides identical electrical specifications and package compatibility. The operating temperature range of -40°C to 85°C covers standard industrial applications, with the upper limit being 40°C lower than the original part. This substitution is appropriate for applications not requiring the extended 125°C upper temperature limit.

M74HC368B1R (STMicroelectronics) serves as an alternative substitute with extended operating temperature range of -55°C to 125°C, matching the original part's upper temperature specification. This part is ROHS3 compliant and suitable for applications requiring the full temperature envelope of the original design.

CD74HC368E (Harris Corporation) is not recommended for new designs due to RoHS non-compliance and Obsolete product status, despite offering the extended temperature range of -55°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can SN74HC368N directly replace 74HC368N in existing designs? A: Yes. Both parts share identical electrical specifications (logic type, element count, bit configuration, output type, current ratings, and supply voltage) and the same 16-DIP package footprint. The operating temperature range difference (-40°C to 85°C versus -40°C to 125°C) requires evaluation only if the application demands operation above 85°C.

Q: What is the difference between 16-DIP and 16-PDIP packaging? A: Both designations refer to the same 16-pin Dual Inline Package with 0.300" (7.62mm) pitch. The "P" in 16-PDIP indicates plastic material. All substitute parts are mechanically and electrically compatible in through-hole mounting applications.

Q: Why is the 74HC368N classified as Obsolete? A: Obsolete status indicates the part is no longer in active production by the original manufacturer. Substitute parts with Active status, such as SN74HC368N from Texas Instruments, provide continuity for ongoing procurement and design support.

Q: Are all substitute parts ROHS3 compliant? A: No. CD74HC368E is RoHS non-compliant. SN74HC368N and M74HC368B1R are both ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: Which substitute should I select for applications requiring -55°C minimum operating temperature? A: M74HC368B1R supports the extended lower temperature limit of -55°C, compared to -40°C for SN74HC368N and the original 74HC368N.
