Key Features
- 6-bit auto-direction-sensing bidirectional level translation between 1.2 V–3.6 V and 1.65 V–5.5 V without a direction-control pin
- Push-pull output drivers enabling up to 100 Mbps data rates with low propagation delay on SPI, UART, and parallel data buses
- 20-pin TSSOP package with OE pin for 3-state bus isolation during power sequencing in multi-voltage embedded systems
Applications
The TXB0106PWR-P is used to interface 6-bit parallel or mixed-signal buses between different voltage domains in embedded systems, such as connecting a 3.3 V MCU to 1.8 V peripherals including sensors, memory, and wireless modules. Its automatic direction sensing eliminates firmware-controlled direction GPIO, simplifying PCB routing and reducing I/O pin overhead in battery-powered IoT and wearable devices. It also serves as a bidirectional interface buffer in FPGA development boards, camera modules, and USB accessory bridges operating across multiple supply rails.

Frequently Asked Questions
What voltage rails does TXB0106PWR-P support on its A and B sides for level translation?
The TXB0106PWR-P supports 1.2 V to 3.6 V on the VCCA side and 1.65 V to 5.5 V on the VCCB side, covering all common logic levels including 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5 V. This wide dual-supply range makes it compatible with the full range of modern MCUs, FPGAs, and 5 V legacy peripherals in a single 6-channel translator.
How fast can data be transferred through TXB0106PWR-P, and what bus protocols does it support?
TXB0106PWR-P supports push-pull data rates up to 100 Mbps, making it compatible with SPI at 50 MHz, high-speed UART, and parallel data buses up to 8-bit width when combined with a second device. The automatic direction sensing responds to signal transitions within a few nanoseconds, allowing bidirectional operation without any firmware direction-control overhead or GPIO toggling delays.
Can TXB0106PWR-P be safely used on an I2C bus with open-drain pull-up topology?
TXB0106PWR-P is not recommended for pure open-drain I2C buses because its internal one-shot output drivers are optimized for push-pull signals and may interfere with open-drain low levels when multiple masters or devices hold lines low. For I2C at 100 kHz to 400 kHz with open-drain topology, TI recommends the PCA9306 or TXS0102. TXB0106PWR-P works correctly on push-pull SPI, UART, and parallel signal lines between 1.8 V and 3.3 V domains.
What is the package footprint of TXB0106PWR-P and how does it compare to larger 8-bit translators?
TXB0106PWR-P is housed in a 20-pin TSSOP measuring approximately 6.5 mm x 4.4 mm at 0.65 mm pitch for 6 bidirectional channels plus supply and OE pins. Compared to TXB0108 in TSSOP-20 (same footprint but 8 channels), the TXB0106PWR-P is pin-compatible in layout but provides 2 fewer channels — making it the better choice only when exactly 6 channels are needed and the 2-channel savings reduces routing congestion.
