The TL16C554FN from Texas Instruments is a quad universal asynchronous receiver/transmitter (UART) with 16-byte FIFOs. It can be used in a variety of applications requiring multiple serial ports, thanks to its four full-duplex channels. The TL16C554FN supports data rates up to 5 Mbps and has flexible baud rate generators that can be programmed to support a wide range of baud rates. It also features programmable byte-level control, allowing the UART to be configured to support 5, 6, 7, or 8-bit data characters with even, odd, or no parity. Additionally, the TL16C554FN supports the IrDA Standard for infrared communication and is compatible with industrial temperature ranges (-40°C to 85°C), making it suitable for harsh environments. Overall, the TL16C554FN is a versatile and reliable UART solution for applications requiring multiple serial ports
