The driver converts TTL-level serial data into differential signals on the A\/B bus lines. The receiver converts differential signals back to TTL. Separate driver enable (DE) and receiver enable (\/RE) pins allow half-duplex operation. The driver features current limiting and thermal shutdown for fault protection.","pin_description":"
