What are the key features of DEL-TXB0101DBVR?
- Automatic direction sensing eliminates the need for a direction control pin, simplifying board design
- Wide dual-supply range (1.2 V–3.6 V on A-side, 1.65 V–5.5 V on B-side) covers virtually all modern logic voltage combinations
- Push-pull output stage enables higher switching speeds compared to open-drain translators, suitable for fast I2C and GPIO signals
- Compact 6-pin SOT-23 package minimizes board space while supporting 1-bit translation in handheld and space-constrained designs
What is DEL-TXB0101DBVR used for?
The TXB0101DBVR is commonly used for single-signal level translation between microcontrollers running at 1.8 V or 3.3 V and peripherals such as sensors, EEPROMs, or legacy 5-V logic. It is also found in portable electronics, IoT devices, and wearables where board area and power budget are tightly constrained.

Frequently Asked Questions
What voltage ranges does the TXB0101DBVR support for level translation?
The A-side supply (VCCA) accepts 1.2 V to 3.6 V, and the B-side supply (VCCB) accepts 1.65 V to 5.5 V. This wide range covers translation between 1.2-V, 1.8-V, 2.5-V, 3.3-V, and 5-V logic systems without additional components.
Does the TXB0101DBVR require a direction control pin?
No, the TXB0101 features automatic direction sensing using an internal edge-detection circuit. The device automatically detects the direction of each signal transition, removing the need for an OE or DIR control signal and simplifying PCB routing.
What type of output does the TXB0101DBVR use?
The device uses push-pull outputs rather than open-drain outputs. This allows faster rise and fall times without external pull-up resistors, making it suitable for GPIO, SPI, and other moderate-speed single-ended signals up to several MHz.
What package is the TXB0101DBVR available in?
The TXB0101DBVR is available in a 6-pin SOT-23 (DBV) package. This surface-mount package has a very small footprint of approximately 2.9 mm x 1.6 mm, making it ideal for compact portable and IoT product designs.
Can the TXB0101DBVR be used for I2C level translation?
For standard I2C, an open-drain translator such as the TCA9406 is generally preferred because I2C uses open-drain signaling. However, if the I2C master drives the line push-pull (as some controllers do), the TXB0101 can work; otherwise use an open-drain-compatible translator for reliable I2C operation.
