Working Principles

SN65LVDS250DBTR operates based on the LVDS signaling standard. It uses a differential voltage swing to represent digital data, where a high voltage level represents logic '1' and a low voltage level represents logic '0'. The differential signaling helps in reducing common-mode noise and provides better noise immunity compared to single-ended signaling.

The transceiver receives parallel data at the A and B inputs and converts it into LVDS signals at the Y and Z outputs. Similarly, it can receive LVDS signals at the Y and Z inputs and convert them into parallel data at the A and B outputs.
