Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74FST6800PGG are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Circuit configuration: 10 x 1:1 bus switch topology
• Independent circuits: 1
• Voltage supply source: Single supply operation
• Operating temperature range: -40°C ~ 85°C
• Mounting type: Surface mount
• RoHS and REACH compliance status
• MSL rating: 1 (Unlimited)

The substitute parts identified are from the Texas Instruments 74CBT6800 series, which maintains functional equivalence through identical circuit topology, operating temperature range, and compliance certifications. Packaging variations exist between substitute options, allowing selection based on procurement and assembly requirements.

Parameter Comparison

Engineering Selection Recommendations

SN74CBT6800CPWR is the primary substitute for new designs and ongoing procurement. This part maintains active product status with Texas Instruments, ensuring long-term availability and supply chain stability. It is supplied in Tape & Reel format, standard for high-volume manufacturing operations. The 24-TSSOP package matches the original 74FST6800PGG footprint exactly.

SN74CBT6800CDGVR is functionally equivalent with identical electrical specifications but uses 24-TVSOP packaging. This variant is suitable for applications where TVSOP package compatibility is required. Active product status ensures continued availability.

SN74CBT6800APWR is available in Cut Tape format and carries Last Time Buy status. This option is appropriate for low-volume applications or prototype development where Cut Tape packaging is acceptable. Supply availability may be limited due to product status transition.

All three substitutes maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can SN74CBT6800CPWR directly replace 74FST6800PGG in existing designs?

A: Yes. Both parts share identical circuit topology (10 x 1:1 bus switch), operating temperature range (-40°C ~ 85°C), and 24-TSSOP package footprint. Pin-for-pin compatibility is maintained.

Q: What is the difference between SN74CBT6800CPWR and SN74CBT6800CDGVR?

A: The primary difference is packaging format. SN74CBT6800CPWR uses 24-TSSOP, while SN74CBT6800CDGVR uses 24-TVSOP. Both maintain identical electrical specifications and operating characteristics. Package selection depends on PCB layout and assembly equipment compatibility.

Q: Why is the 74FST6800PGG obsolete?

A: The 74FST6800PGG is classified as obsolete by Renesas Electronics. The Texas Instruments 74CBT6800 series provides equivalent functionality and is actively maintained, making it the recommended replacement path.

Q: Are there any voltage supply differences between the main part and substitutes?

A: The 74FST6800PGG does not specify voltage supply parameters in available documentation. The SN74CBT6800 series operates at 4V ~ 5.5V single supply. Design verification is required to confirm compatibility with your specific application voltage requirements.

Q: What packaging formats are available for the SN74CBT6800 series?

A: Three packaging options are available: Cut Tape (CT) for SN74CBT6800APWR, Tape & Reel (TR) for SN74CBT6800CPWR, and Tape & Reel (TR) for SN74CBT6800CDGVR. Selection depends on procurement volume and assembly process requirements.

Q: Do all substitutes maintain the same compliance certifications?

A: Yes. All substitute parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) rating, matching the original 74FST6800PGG specifications.
