The SN75LBC180N is a low-power, high-speed transceiver communication interface IC manufactured by Texas Instruments. It supports the RS-485 serial communications protocol, which enables multiple devices to exchange data and control signals over a common bus. The chip offers three-state logic buffers, which allow data to be communicated on the bus without impacting the idle state of the other lines. It also features extended Common Mode range, low-power shutdown mode, and fault protection circuitry. It is adapted to be used in industrial applications such as automation, building control, and energy management.
