Overview
The TXS0102DCURG4 is a 2-bit bidirectional voltage-level translator manufactured by Texas Instruments. It operates with a VCCA supply range of 1.65 V to 3.6 V and a VCCB supply range of 2.3 V to 5.5 V, enabling translation between different logic families. The device supports data rates up to 24 Mbps and features automatic direction sensing. It is housed in an 8-pin VSSOP package and functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Supports bidirectional voltage translation between low-voltage (1.65V) and high-voltage (5.5V) logic domains
- Features automatic direction sensing for seamless signal flow without explicit control pins
- Capable of handling data rates up to 24 Mbps for high-speed interface applications
Applications
- Interfacing low-voltage microcontrollers with higher-voltage peripherals
- Level shifting for I2C, SPI, and other multi-master bus systems
- Connecting mixed-voltage digital circuits in embedded systems
Procurement Notes
Verify the specific suffix G4 indicates RoHS compliance and green material status as per Texas Instruments documentation. Confirm the VSSOP-8 package dimensions match your PCB footprint requirements. Ensure the supply voltages on both sides remain within the specified 1.65V–3.6V and 2.3V–5.5V ranges during operation to maintain signal integrity.
Selection Notes
Select this component when bidirectional translation is required between 1.65V and 5.5V logic levels. It is suitable for applications needing automatic direction detection without additional control signals. Consider the 24 Mbps data rate capability for high-speed interfaces. Verify that the VSSOP-8 package fits the available board space and thermal constraints.
Part Context
This part belongs to the Texas Instruments TXS0102 series of bidirectional voltage-level translators. It is designed to replace older level-shifting solutions by offering integrated direction sensing and wider voltage compatibility. The DCUR variant specifically denotes the tape-and-reel packaging format for surface-mount assembly.
Replacement Considerations
Direct replacements include the TXS0102DCUR, which shares identical electrical characteristics but may differ in packaging suffix or manufacturing lot specifications. Verify pinout compatibility and ensure the substitute maintains the same VSSOP-8 form factor.
