The LSF0102-Q1 device is an auto bidirectional voltage translator that translates among awide range of supplies without the need for a directional pin. The LSF0102-Q1 supports up to 100MHz up translation and greater than 100 MHz down translation with capacitive loads ≤ 30 pF.Additionally, the LSF0102-Q1 supports up to 40 MHz up and down translation at 50 pF capacitanceload, which enables the LSF0102-Q1 device to support a wide variety of standard interfaces commonlyfound in automotive applications such as I2C, SPI, GPIO, SDIO, UART, andMDIO.

The LSF0102-Q1 device has 5-V tolerant data inputs. This makes the device compatible withTTL voltage levels. Furthermore, the LSF0102-Q1 supports mixed-mode voltage translation, allowingthe device to up translate and down translate to different supply levels on each channel.
