Working Principles

The SN65LV1021DBR operates by receiving differential input signals on pins A and B. These signals are amplified, filtered, and level-shifted to match the desired output voltage levels. The converted signals are then transmitted differentially through pins Y and Z. The device can be controlled using the /RE and DE pins, which enable/disable the driver and receiver sections, respectively.
