XBLW MAX490ESA(XBLW)

The MAX490, which is used for RS-485/RS-422 communication, is a high-speed transceiver with full-duplex communication that includes a driver and a receiver. When the receiver input is open or shorted, it ensures that the receiver output is at a logic high level. If all transmitters attached to the terminated matching bus are disabled (high-impedance), the receiver will output a logic high level. The MAX490 has a low-rate driver that can reduce EMI and reflections caused by improper terminal matching cables, and achieve error-free data transfer rates up to 2.5Mbps. In addition, the MAX490 has a 1/8 unit load input impedance, and up to 256 transmitters and receivers can be attached to the bus.
