UART Interface ICs

Universal Asynchronous Receiver Transmitter (UART) interface is an integrated circuit (IC) used to implement serial digital interfaces.

Interface ICs are integrated circuits that control and manage communication between two or more devices. A UART IC converts data between parallel and serial forms, making it indispensable in systems where devices need to communicate via serial ports. It's the standard serial interface for PCs and microcontrollers. Whether you're developing applications for computing, telecommunications or embedded systems, we'll help you find the latest and most reliable UART ICs available from the manufacturers you trust.
