, Logic-Translators, Level Shifters The LSF0102DCUR is a two-channel, two-directional level shifter from Texas Instruments. It mounts on an 8-lead SOIC package and is optimized for USB-C connections. It is designed to be used for small switch applications in USB-C applications, but can also be used for motor control applications and other 3.3V-5V applications. The LSF0102DCUR is based on TI’s unique combination of control logic and precision level shifting. The internal control logic allows for a single-pin, two-way communication interface without the need for external control logic or external logic levels. The precision level shifting is accomplished by an internal FET to balance the output voltage versus the input voltage, and to ensure excellent signal integrity and maximum noise immunity. The LSF0102DCUR is a compact, low-power solution optimized for optimal signal integrity and noise immunity. It is capable of supporting dual-direction data transfer up to 5Mbps and is ideal for small switch applications such as USB-C applications. It can operate with multiple power rails ranging from 1.8V to 5.5V and supports USB-C application protocols up to 5V. The LSF0102DCUR\'s level-shifting capability allows it to successfully bridge the gap between logic levels by providing precision level shifting without the need for external logic level converters. It also enables it to provide additional protection from electrical interference, surges, and EMI, making it an ideal solution for applications requiring reliable signal integrity. When used for USB-C applications, the LSF0102DCUR can interface between the host-side logic and the peripheral-side logic over a USB-C link. It can enable USB-C host detection by automatically detecting USB signals on both sides of the connection. The device can also switch between the USB-C connector on the host side and the USB-C connector on the peripheral side, allowing the host to communicate directly with peripherals. Finally, the LSF0102DCUR is designed to perform safety and feature detection in USB-C applications. It can identify the presence of USB-C charging and audio/video accessories connected to the device and also contains built-in fault protection features that protect against reverse/over-voltage and over-current conditions. In conclusion, the LSF0102DCUR is a low power and cost-effective level shifter, designed to help bridge the gap between various logic levels and to provide signal integrity and noise immunity. With its ability to support high-speed data transfers and provide failure protection, it is the ideal solution for small switch applications and other USB-C and 3.3V-5V applications.
