Fail-safe receiver ensures logic-high output when bus is idle or all drivers disabled.","working_principle":"The driver converts single-ended TTL\/CMOS logic to differential RS-485 levels (A-B > 1.5V for logic 1, A-B < -1.5V for logic 0). The receiver converts differential bus levels back to single-ended logic. The half-duplex architecture shares A\/B pins between driver and receiver with enable\/disable controls. The 3.3V supply reduces power versus 5V transceivers. Current limiting and thermal shutdown protect the driver from bus faults.","pin_description":"
