LSF010x/LSF010x-Q1 Level Translators Texas Instruments LSF010x/LSF010x-Q1 Level Translators support bidirectional voltage translation without needing a DIR pin which minimizes system effort (for PMBus, I2C, SMBus, etc.). The LSF010x/LSF010x-Q1 supports up to 100MHz up translation and greater than 100MHz down translation at ≤30pF capacitive load. Additionally, these devices support up to 40MHz up/down translation at 50pF capacitance load. These features enable the device to support more consumer or telecom interfaces (MDIO or SDIO).
