MAX3491ESD+

MAXIM INTEGRATED PRODUCTS  MAX3491ESD+  芯片, RS422/RS485 收发器, 10MBPS, 3.6V, NSOIC-14

The is a 3.3V powered, true RS485/RS422 transceiver in 14 pin NSOIC package. The device has transmission data rate up to 10Mbps. The driver is short circuit current limited and protected against excessive power dissipation by thermal shutdown circuitry that places the driver output into a high impedance state. The receiver input has a fail-safe feature that gives a logic high output if both inputs are open circuit.
