Frequently Asked Questions
What is the SN74CBT3306CPW and what does it do?
The SN74CBT3306CPW is a dual FET bus switch from Texas Instruments with -2V undershoot protection. It provides unidirectional switching with an active-low enable pin, supports 1-bit operation with up to 50pF load capacitance, and is housed in a compact TSSOP-8 package, making it ideal for data bus isolation and signal switching in mixed-voltage systems.
What voltage levels does the SN74CBT3306CPW support?
The SN74CBT3306CPW supports both 3.3V and 5V logic systems. Its FET-based architecture provides low ON-state resistance and the -2V undershoot protection ensures signal integrity when interfacing between different voltage domains, making it suitable for mixed-voltage board designs common in embedded and consumer electronics.
What package type is the SN74CBT3306CPW and what are the PCB layout considerations?
The SN74CBT3306CPW comes in a TSSOP-8 (R-PDSO-G8) small outline package. For PCB layout, keep bypass capacitors close to the VCC pin, use short trace lengths for high-speed switching paths, and ensure proper ground plane coverage to minimize noise. The compact 8-pin footprint is well-suited for space-constrained designs.
Are there alternative parts or substitutes for the SN74CBT3306CPW?
Compatible alternatives include other members of the Texas Instruments CBT/FST bus switch family. Parts such as the SN74CBT3306 in different packages (SOIC, SOT) offer the same dual FET switching with -2V undershoot protection. FST-family devices from other manufacturers like Nexperia or ON Semiconductor may also serve as functional substitutes with similar specifications.
Where can I buy the SN74CBT3306CPW and what is the typical price?
The SN74CBT3306CPW is available from authorized distributors worldwide with pricing starting from approximately $0.41 per unit. Volume pricing is available for larger quantities. FindMyChip offers a quick quote service for bulk orders with worldwide shipping, ensuring you can source this Texas Instruments bus switch efficiently for your production needs.
