NXS, NXB, LSF AutoSense Translation Transceivers Nexperia NXS, NXB, LSF AutoSense Translation Transceivers offer automatic bidirectional sensing for interface voltage level translation. Voltage translation is used to ensure that devices operating at different supply voltages in a system are able to work with each other without any damaging current flow and signal loss. These 1-bit, 2-bit, 4-bit, and 8-bit devices can be used in both push-pull and open-drain-based applications without the use of an additional direction pin.
