With an unlimited slew rate driver, it supports data rates up to 2.5Mbps for half-duplex communication. The driver output features short-circuit current limiting and thermal shutdown protection, while the receiver includes a fail-safe feature guaranteeing a logic-high output when the input is open-circuit. The device supports up to 32 transceivers on a single bus with 1\/8 unit load input impedance.","working_principle":"The MAX485ESA+T integrates a differential driver and a differential receiver with independent enable controls (DE for driver, \/RE for receiver). The driver converts single-ended TTL\/CMOS logic to differential RS-485 signals on the A and B bus pins. The receiver converts the differential bus signal back to single-ended logic on the RO pin. In half-duplex mode, only the driver or receiver is active at a time, controlled by DE and \/RE pins. When both are disabled, the device enters a low-power shutdown mode. The fail-safe receiver ensures a defined high output state when the bus is idle or floating.","pin_description":"
