Interface ICs (integrated circuits) are electronic devices that are used to connect two or more separate devices or systems. These ICs typically provide a communication interface between the devices, allowing them to exchange information and data.
RS-485/RS-422 ICs are a type of interface IC that is used in serial communication systems. RS-485 and RS-422 are both standards for balanced serial communications, and they are often used in industrial and commercial applications. RS-485/RS-422 ICs are used to convert between the electrical signals used in these communication systems and the digital signals used by computers and other electronic devices.
