PRODUCTION DATA
An RS-485 bus consists of multiple transceivers connecting in parallel to a bus cable. To eliminate line reflections, each cable end is terminated with a termination resistor, RT, whose value matches the characteristic impedance, Z0, of the cable. This method, known as parallel termination, generally allows for higher data rates over longer cable length.
THVD4411 can be used in both networks (half and full duplex) and at all nodes (end node or middle nodes) since device has the configurability based on MODE1, MODE0 pins and TERM_TX, TERM_RX pins.
THVD4411 also consists of one line driver, one line receiver and dual charge pump circuit to enable RS-232 serial communication port. This device provides the electrical interface between an asynchronous communication controller and the serial-port connector.
