PI5C6800L Bus Switch 10 x 1:1 Equivalent & Substitute Parts

Part Overview

The PI5C6800L is a Bus Switch IC manufactured by Diodes Incorporated, configured as a 10 x 1:1 multiplexer in a 24-TSSOP package. This component is classified as Obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. The part operates with single supply voltage between 4V and 5.5V across an operating temperature range of -40°C to 85°C. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PI5C6800L is determined by strict adherence to the following parameters:

• Circuit Type & Configuration: All substitutes must be Bus Switch ICs with 10 x 1:1 multiplexer configuration
• Voltage Supply: Single supply operation within 4V to 5.5V range (note: SN74CBT3861PWR operates 4.5V ~ 5.5V, which is a subset of the required range)
• Operating Temperature: -40°C to 85°C minimum requirement
• Package Compatibility: 24-TSSOP or equivalent footprint (24-TVSOP acceptable for pin-compatible variants)
• Mounting Type: Surface Mount only
• Moisture Sensitivity: MSL 1 (Unlimited) classification

The substitute parts listed below meet these criteria and are available from Texas Instruments under the 74CBT series designation.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: SN74CBT6800CPWR

The SN74CBT6800CPWR is the optimal substitute for the PI5C6800L. This part maintains identical electrical specifications (4V ~ 5.5V supply, -40°C ~ 85°C operating range) and package format (24-TSSOP). The device carries Active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. Tape & Reel packaging supports high-volume production requirements.

Secondary Recommendation: SN74CBT6800APWR

The SN74CBT6800APWR provides full electrical and mechanical compatibility with identical voltage and temperature specifications. This part is designated Last Time Buy, indicating limited future availability. Use this option only when SN74CBT6800CPWR inventory is constrained.

Alternative for Package Flexibility: SN74CBT6800CDGVR

The SN74CBT6800CDGVR offers identical electrical performance in a 24-TVSOP package variant. This option is suitable for designs where TVSOP footprint compatibility exists. Active product status ensures ongoing supply.

Not Recommended: SN74CBT3861PWR

While functionally equivalent in circuit configuration, the SN74CBT3861PWR operates within a restricted voltage range (4.5V ~ 5.5V). This part is unsuitable for applications requiring operation at 4V supply levels. Use only when 4.5V minimum supply voltage is acceptable for the target application.

Frequently Asked Questions (FAQ)

Q: Can the PI5C6800L be directly replaced with SN74CBT6800CPWR without PCB modifications?

A: Yes. Both parts use identical 24-TSSOP packaging with matching pin assignments and electrical specifications. Direct socket substitution is possible without PCB layout changes.

Q: What is the difference between SN74CBT6800CPWR and SN74CBT6800CDGVR?

A: Both parts share identical electrical specifications and base product number (74CBT6800). The primary difference is package format: SN74CBT6800CPWR uses 24-TSSOP, while SN74CBT6800CDGVR uses 24-TVSOP. Footprint compatibility must be verified before substitution.

Q: Why is SN74CBT3861PWR listed as a substitute if it has a different voltage range?

A: SN74CBT3861PWR maintains the same 10 x 1:1 bus switch configuration and package format. However, its 4.5V minimum supply voltage represents a constraint compared to the PI5C6800L's 4V minimum. This part is suitable only for designs operating at 4.5V or higher.

Q: What does "Last Time Buy" status mean for SN74CBT6800APWR?

A: Last Time Buy indicates the manufacturer has announced end-of-life for this part. Existing inventory may be available, but no future production is planned. For new designs, select SN74CBT6800CPWR (Active status) to ensure long-term supply continuity.

Q: Are all substitute parts RoHS compliant?

A: All Texas Instruments substitutes (SN74CBT series) carry ROHS3 compliance. The original PI5C6800L is RoHS non-compliant. Designs requiring RoHS certification must transition to one of the substitute parts.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity limitations. Storage and handling do not require special moisture control measures, simplifying logistics and inventory management for both the original part and all substitutes.
