What are the key features of TXS0108EPWR?
- 8-bit bidirectional auto-direction-sensing level translation between 1.2 V–3.6 V and 1.65 V–5.5 V rails with no direction-control pin required
- Push-pull outputs enabling high-speed data transfer up to 110 Mbps with ≤4.8 ns propagation delay
- 3-state output capability and OE pin for bus sharing across multiple devices on the same I/O line
What is TXS0108EPWR used for?
The TXS0108EPWR is ideal for interfacing mixed-voltage logic buses in embedded systems, such as connecting a 3.3 V microcontroller to 1.8 V DDR memory, SPI flash, or I2C sensors. Its automatic direction sensing eliminates the need for external direction control signals, simplifying firmware and PCB design in battery-powered IoT devices and wearables. It is also used in USB accessory interfaces, camera module adapters, and FPGA I/O expansion boards that mix multiple supply rails.

Frequently Asked Questions
What voltage rails does the TXS0108EPWR support on each side of the level translator?
The TXS0108EPWR supports 1.2 V to 3.6 V on the A-side and 1.65 V to 5.5 V on the B-side, enabling translation between common logic families including 1.2 V, 1.8 V, 2.5 V, 3.3 V, and 5 V. This wide range covers most embedded and industrial mixed-voltage bus scenarios without additional level-shift stages.
How fast can data be transferred through the TXS0108EPWR on a push-pull bus?
The TXS0108EPWR achieves up to 110 Mbps data rates on push-pull driven lines with a maximum propagation delay of 4.8 ns. This performance is adequate for SPI at 80 MHz, parallel data buses, and camera interfaces, making it one of the faster auto-direction-sensing 8-bit translators in the SSOP-20 form factor.
Can the TXS0108EPWR be used on an open-drain I2C bus running at 400 kHz?
The TXS0108EPWR is not optimally suited for open-drain I2C buses because its internal weak pull-ups may not drive lines fast enough at 400 kHz Fast-mode without external resistors of around 1 kΩ to 4.7 kΩ. For pure open-drain topologies, TI recommends the PCA9306 or TXB series with pull-up resistors, but TXS0108E can work in mixed open-drain/push-pull designs at 100 kHz Standard-mode with proper pull-up sizing.
When would TXS0108EPWR be preferred over TXB0108 for a 3.3 V to 1.8 V interface?
TXS0108EPWR is preferred when the design requires 3-state outputs and bus sharing across 8 channels, since its OE pin allows safe hi-Z isolation during power sequencing. TXB0108 operates similarly but lacks 3-state control. In designs with multiple devices sharing the same 8-bit bus, the TXS0108EPWR's OE-controlled 3-state outputs prevent bus contention at 1.8 V to 3.3 V interfaces.
