Tudi MAX488EEPA-TUDI

MAX488E is a low-power RS-485 and RS-422 transceiver designed for harsh environments. The driver outputs and receiver inputs feature ±15kV ESD protection and are latch-up free. The device contains one driver and one receiver. The MAX488E employs a slew-rate-limited driver to minimize EMI and reduce signal reflections caused by improperly terminated cables, enabling error-free data transmission at up to 250kbps. These transceivers consume only 120μA of supply current when the driver is disabled and the bus is fully loaded. All devices operate from a single 5V supply. Short-circuit current limiting and thermal shutdown circuitry protect the device by forcing the outputs into a high-impedance state to prevent excessive power dissipation. The receiver includes a failsafe feature that guarantees a logic-high output when the input is open. The MAX488E is designed for full-duplex communication.
