Overview
The LSF0108PWR is an 8-bit bidirectional voltage-level translator designed for multi-voltage digital signal translation. It is widely used in I²C, SPI, UART, and GPIO interfaces, where low power consumption, automatic direction sensing, and wide voltage compatibility are required.
Core Parameters
| Parameter | Value |
|---|---|
| Channels | 8-bit |
| Voltage Range (VrefA / VrefB) | 1.1 V to 5.5 V |
| Direction Control | Automatic (no DIR pin) |
| Data Rate | Up to 60 Mbps (push-pull) |
| Supply Current (Typical) | Ultra-low |
| Package | TSSOP-20 (PWR) |
These parameters make the device suitable for mixed-voltage digital systems, especially where bidirectional communication and low-power operation are critical.
