XBLW MAX485EDTR(XBLW)

MAX485 is 3V to 5.5V power supply, ±15kV anti-static slow limit differential transceiver and can provide complete RS485 compatibility for half-duplex applications. Each section contains a driver and a receiver designed for data transmission over an extended common-mode range (-7V to +12V). It can effectively transmit data at a high rate of up to 10Mbps. Drivers are short-circuit current limited and are protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high-impedance state. The Rx input has a fail-safe feature that guarantees a logic-high output if the input is open circuit, shut-circuit and shutdown but not drive. Both components have power-on/off modes, and fault-free driver outputs allow transceivers to be inserted or removed from bus in real time. CMOS designs aim to offer significant power savings without sacrificing overload or ESD damage. Typically, static current is only 300uA in operation and 1uA in shutdown mode.
