In summary, there are three different families of autosense translators available from Nexperia. The LSF family, which provides only a pass transistor and requires external pull-up resistors for operation. The NXS family, which also uses a pass transistor but also adds one-shots for acceleration of rising edges only. Finally, the NXB family which uses push-pull output drives instead of a pass transistor and has one-shots for acceleration of both rising and falling edges in both directions. These three families can provide solutions for high-speed translations across a wide range of voltages for protocols such as I²C, SMBus, SPI, UARTs, and others. The customer's particular solution will depend on the drive power required and the rise and fall times for the specific application.
