• Independent Circuits: 2 circuits per device
• Package Type: 8-TSSOP with identical 0.173" (4.40mm) width
• Mounting Type: Surface mount technology
• Voltage Supply Range: Compatibility within specified operating voltage window
• Operating Temperature Range: -40°C to 85°C minimum coverage
• Compliance Standards: ROHS3 compliance and REACH unaffected status

The substitute parts identified below meet all electrical and mechanical parameters required for direct functional replacement in the PI5C3305LE application space.

Parameter Comparison

Engineering Selection Recommendations

Both Texas Instruments SN74CBT3305 variants (SN74CBT3305CPW and SN74CBT3305CPWR) are qualified substitutes for the PI5C3305LE. The primary distinction between these alternatives is packaging format:

SN74CBT3305CPW is supplied in Tube packaging, matching the original PI5C3305LE format. This variant is suitable for applications requiring standard tube-based component handling and storage.

SN74CBT3305CPWR is supplied in Tape & Reel (TR) format, optimized for automated assembly processes and high-volume production environments.

Both parts maintain Active product status with Texas Instruments, ensuring long-term availability and continued manufacturing support. All three parts (original and substitutes) carry identical ROHS3 compliance and REACH unaffected certifications, confirming regulatory alignment for regulated industries and export applications.

The voltage supply range for Texas Instruments variants (4.5V ~ 5.5V) represents a narrower specification window compared to the Diodes part (4V ~ 5.5V). Applications operating at supply voltages below 4.5V require verification against specific circuit requirements before substitution.

Frequently Asked Questions (FAQ)

Q: Can SN74CBT3305CPW and SN74CBT3305CPWR be used interchangeably with PI5C3305LE?

A: Yes. Both Texas Instruments parts are electrically and mechanically equivalent to the PI5C3305LE. The difference between them is packaging format only: CPW uses Tube packaging while CPWR uses Tape & Reel format. Selection depends on your assembly process requirements.

Q: What is the key difference in voltage supply specifications?

A: The PI5C3305LE operates from 4V to 5.5V, while both SN74CBT3305 variants operate from 4.5V to 5.5V. If your circuit operates at 4V to 4.5V, the PI5C3305LE is required. For applications at 4.5V and above, all three parts are compatible.

Q: Are the pin configurations identical?

A: Yes. All three parts use the 8-TSSOP package with identical pin assignments and functional layout, enabling direct PCB footprint compatibility without design modification.

Q: Why is the PI5C3305LE marked as Last Time Buy?

A: Last Time Buy status indicates Diodes Incorporated is discontinuing this part number. Existing inventory is available, but no future production is planned. The Texas Instruments SN74CBT3305 series remains in Active production status.

Q: Which substitute should I select for new designs?

A: For new designs, either Texas Instruments SN74CBT3305 variant is appropriate. Choose SN74CBT3305CPW for manual assembly or standard procurement workflows, or SN74CBT3305CPWR for automated high-volume manufacturing.

Q: Are all three parts RoHS3 compliant?

A: Yes. The PI5C3305LE, SN74CBT3305CPW, and SN74CBT3305CPWR all carry ROHS3 compliance certification and REACH unaffected status, meeting environmental and regulatory requirements for EU and global markets.
