This document describes the features and characteristics of the SLLS397A model, including support for multiple input clocks, large capacity FIFO buffers, programmable flow control, and interrupt generation.
The TL16C754B is a quad universal asynchronous receiver/transmitter (UART) featuring 64‑byte transmit and receive FIFOs, automatic hardware/software flow control, and data rates up to 3 Mbps. It offers programmable baud‑rate generation, selectable parity, stop bits, and supports both 3.3 V and 5 V supplies.
The device is pin‑compatible with TL16C554 and ST16C654, available in 80‑pin TQFP and 68‑pin PLCC packages. Detailed functional blocks, terminal functions, and flow‑control options (auto‑CTS/RTS, Xon/Xoff) are described, along with package dimensions and warranty notices.
