Overview
The SN74CBTD1G384DBVT is a single-channel, 1:1 digital bus switch manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in an SC-70-5 package. The device functions as a bidirectional data selector with level shifting capabilities, designed for low-power applications across an operating temperature range of -40°C to +85°C.
Feature Summary
- Provides a single bidirectional channel for signal routing between two domains
- Integrates internal level shifting to manage voltage differences between input and output sides
- Features low on-resistance characteristics suitable for high-speed data transmission
Applications
- Level translation between different voltage domains in portable electronics
- Signal switching in mobile communication devices
- Data line protection and selection in consumer appliances
Procurement Notes
Verify the specific suffix 'DBVT' corresponds to the SC-70-5 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to integration. Ensure the selected component matches the required voltage specifications for the target application circuit.
Selection Notes
Select this component when a single-channel bidirectional switch with integrated level shifting is required. It is appropriate for designs needing voltage domain translation between 5V systems. Consider the compact SC-70-5 package for space-constrained layouts. Verify that the 4.5V to 5.5V supply range aligns with the system power architecture.
Part Context
This part belongs to the SN74CBTD1G series of single-gate bus switches from Texas Instruments. These components are engineered for low-voltage and low-power applications requiring efficient signal routing. The series offers various package options to accommodate different board space requirements while maintaining consistent electrical performance standards.
Replacement Considerations
Check for SN74CBTD1G384DCKR which shares the same functional core but utilizes a SOT-353 (SC-70-5) package. Verify pinout compatibility and thermal characteristics before substituting. Consult the manufacturer's cross-reference guide for other compatible variants within the CBTD family.
