.The TL16C554AIPNR is a Texas Instruments UART Interface IC Quad UART with 16-Byte FIFOs. This device is a 4-wire interface UART IC, capable of operating at data rates up to 8 Mbps. It has four separate 16-byte FIFOs that allow for data to be read or transmitted independently in a multichannel system. Additionally, the TL16C554AIPNR features a register set that can be accessed to retrieve various signaling information from the UART IC or to select various operating modes. It also comes with on-die address recognition and automatic wake-up, which allows for power conservation in a number of applications. The TL16C554AIPNR is a simple, high-speed, versatile solution for many UART applications, and its use can help minimize the number of external components required.
