نظرة عامة على المنتج
The MAX485CSA+T from Analog Devices (formerly Maxim) is a +5V RS-485/RS-422 transceiver with 2.5Mbps data rate in an SOIC-8 package. With 1/4 unit load (allowing 128 devices on bus), +/-7kV ESD protection on bus pins, and slew-rate limited output for reduced EMI, it is the industry-standard RS-485 interface IC.
