The SN75LBC184DR with SOP-8 RS-485/RS-422 ICs ROHS is a RoHS compliant integrated circuit module manufactured by Youtai. It is a low power, half duplex RS-485/RS-422 transceiver built with CMOS for 3V to 5.5V single-supply operations. The device features user selectable 120? termination resistor, along with bus-pins by an external resistor. It has a TTL-compatible logic interface that allows the device to be configured for both Slave- and Master-Mode operation and provides support for up to 32 drivers/receivers on a single bus. The module supports both differential and single-ended communications and can be used as either a transmitter or a receiver. The device is suitable for applications such as industrial automation, communication networks, data acquisition systems, and instrumentation.
