The ST485XN family of transceiver devices provides full-duplex operation for balanced data communication on digital bus transmission lines. This family of devices is used in RS-485 and RS-422 communications standards. The devices feature 10 Mbps data rates, a ±15 kV ESD protection on all pins, full power-off shutdown, low turn-off time, typical propagation delay of 350 ns, low power mode for minimum system power consumption, 0 V to 5 V logic level compatibility, and an operating temperature range of -40 to +85 °C.

Industrial automation systems are often required to use different types of networks such as CANopen, Modbus, EtherNet/IP, Profibus, etc. The ST485XN transceivers are ideal choice to be used in such industrial networks. It is capable of providing reliable communications in such environments since it is both ESD and surge protected. It also has very low power consumption and precise timing characteristics.

ST485XN transceivers can be used to transmit and receive data over balanced data communication line. The device has two interoperable drivers and two interoperable receivers. The drivers incorporate a differential output stage to provide a robust line driver solution for RS-485 and RS-422 networks. The drivers feature a 19 mA sink current and a 25 mA source current, a ±15 kV ESD protection and an enable/disable pin. The receivers are high gain and low power devices with a 7 ns typical input signal noise filter.

Working principle of the ST485XN transceiver is simple and straightforward. When transmit mode is enabled, the input signal is transferred through the differential line driver, which encodes it using differential voltage levels. The differential output signals are sent out of the device to the transmission line, where they are received by the receiver. The receiver then decodes the signal and sends it out as an output signal.

ST485XN transceivers are used in a variety of applications, including industrial network control, modems, bus coupling interfaces, fieldbus systems and multiple master systems. They are also used in embedded systems and wired communications applications. In addition, they can be used in automotive and automotive related applications, medical devices, as well as aerospace and avionics equipment.

In conclusion, the ST485XN transceivers provide a robust, reliable and feature packed solution for serial communication. They are used in a variety of applications in the industrial, automotive and aerospace markets, thanks to their robustness and low power consumption. They are well suited for point-to-point, multi-point and full-duplex transmission lines because of their differential output line driver and high gain receiver.
