Overview
The SN74CBT3305CPWRG4 is a dual FET bus switch manufactured by Texas Instruments. It features a single circuit configuration with a 1:1 ratio, housed in an 8-TSSOP package. The device operates within a temperature range of -40°C to 85°C and includes undershoot protection down to -2 V. This component belongs to the 74CBT series and is designed for signal switching applications requiring low on-resistance and high bandwidth.
Feature Summary
- Dual FET architecture providing efficient signal path control
- Integrated undershoot protection capable of handling -2 V signals
- Compact 8-pin TSSOP packaging suitable for space-constrained designs
Applications
- Portable equipment requiring low power consumption
- Consumer electronics utilizing high-speed data buses
- Industrial systems needing reliable signal routing
Procurement Notes
Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status as per Texas Instruments documentation. Confirm the tape and reel packaging format matches your automated assembly requirements. Ensure the operating temperature range aligns with your system's environmental specifications before finalizing procurement.
Selection Notes
Select this component when a single-channel bus switch with robust undershoot protection is required. The 8-TSSOP package offers a balance between pin count and board space. Consider the 74CBT series characteristics for low distortion and high-speed performance in digital signal paths.
Part Context
This part is part of the broader 74CBT family of bus switches from Texas Instruments. It shares functional similarities with other devices in the series but is distinguished by its specific circuit count and package type. The SN74CBT3305C variant serves as the base model for this configuration.
Replacement Considerations
Direct substitutes may include other SN74CBT3305 variants such as SN74CBT3305CPW or SN74CBT3305CPWR, provided the package and electrical characteristics match. Verify pin compatibility and thermal performance before substitution.
