Overview
The SN74CBT1G125DBVT is a single Field-Effect Transistor (FET) bus switch manufactured by Texas Instruments. It operates within a supply voltage range of 2.5 V to 3.6 V and features a 5-V tolerant level shifter for input signals. The device provides powered-off protection to prevent current leakage when the power supply is off. It is housed in a SC-70 or SOT-23-5 package, suitable for surface-mount applications.
Feature Summary
- Integrates a single FET signal path with 5-V tolerant level shifting capabilities
- Provides powered-off protection to isolate the signal path during power-down states
- Operates on low-voltage supplies ranging from 2.5 V to 3.6 V
Applications
- Low-voltage bus switching in portable electronic devices
- Signal translation between different voltage domains
- Battery-powered equipment requiring powered-off isolation
Procurement Notes
Verify the specific suffix 'VT' against the manufacturer's official documentation to confirm the tape-and-reel packaging configuration and quantity per reel. Ensure the component meets the required operating temperature range and electrostatic discharge ratings for the intended application environment before finalizing procurement.
Selection Notes
Select this component when a single-channel bus switch is required for low-voltage systems operating between 2.5 V and 3.6 V. The 5-V tolerant input allows compatibility with higher voltage logic levels without external level shifters. Consider the SC-70/SOT-23-5 package size for space-constrained designs.
Part Context
This part belongs to the SN74CBT1G125 family of single FET bus switches. It is designed for low-voltage applications where signal integrity and power efficiency are critical. The device serves as a bridge for data transmission between circuits operating at different voltage levels.
Replacement Considerations
Consult the manufacturer's cross-reference guide for verified substitutes. Ensure any replacement maintains the same voltage range, package type, and 5-V tolerance specifications.
