MAX3292ESD+T

MAX3292ESD+T is a RS-485/RS-422 transceiver with pre-emphasis for high-speed, long-distance communication. It features driver pre-emphasis circuitry, which extends the distance and increases the data rate of reliable communication by reducing intersymbol interference (ISI) caused by long cables. It is programmable for data rates up to 10Mbps by using a single external resistor. It is a full-duplex device that operates from a single +5V supply and offers a low-current shutdown mode that reduces supply current to 100nA. They feature driver output short-circuit current limiting and a fail-safe receiver input that guarantees a logic-high output if the input is an open circuit. A 1/4-unit load receiver input impedance allows up to 128 transceivers on the bus. Typical applications are long-distance, high-speed RS-485/RS-422, communications, telecommunications, industrial-control local area networks.
