Key Features
- 8-bit bidirectional voltage level translation (1.8V–5.5V)
- Open-drain outputs with ultra-low propagation delay of 2.2ns max
- Single supply operation, no direction pin required
- 20-pin TSSOP package (LSF0108PWR) for compact board designs
- Compatible with I2C and other open-drain bus interfaces
Applications
The LSF0108PWR is widely used in mixed-voltage embedded systems where I2C, SMBus, or other open-drain buses must cross voltage domains, such as between a 3.3V microcontroller and 1.8V sensors or memory devices. It is also suitable for battery-powered IoT devices, wearables, and portable consumer electronics that require low-power level shifting between different logic levels.

Frequently Asked Questions
What voltage ranges does the LSF0108PWR support for level translation?
The LSF0108PWR supports bidirectional voltage level translation between 1.8V and 5.5V. The VREF_A pin can be set from 1.0V to 3.6V and VREF_B from 1.8V to 5.5V, making it compatible with common logic levels including 1.8V, 2.5V, 3.3V, and 5V systems.
What is the maximum operating speed of the LSF0108PWR?
The LSF0108PWR has a maximum propagation delay of 2.2ns, enabling high-speed bidirectional level translation. It supports data rates suitable for I2C, SPI, and other standard serial interfaces commonly used in embedded and industrial applications.
Why does the LSF0108PWR use open-drain outputs, and what does this mean for my design?
The LSF0108PWR uses open-drain outputs to enable safe bidirectional level translation without the risk of bus contention. This means each I/O line requires an external pull-up resistor to the appropriate supply voltage (VREF_A or VREF_B side). This topology is ideal for multi-master bus interfaces such as I2C and allows devices operating at different voltages to share the same bus.
