PHILIPS SC16C554 SC16C554D UART
The Philips SC16C554/554D is a 4-channel Universal Asynchronous Receiver and Transmitter (UART) designed for serial data communications. It converts parallel data into serial data and vice versa, supporting data rates up to 5 Mbit/s. The device is pin compatible with the ST16C554 and TL16C554 and offers an Intel or Motorola interface.
Key features include 16-byte receive and transmit FIFOs, automatic hardware or software flow control, and Infrared (IrDA) encoding/decoding capabilities. The chip operates at 5 V, 3.3 V, and 2.5 V and is available in PLCC68, LQFP64, and LQFP80 packages.

Questions answered in these manuals
What is the maximum data rate of the SC16C554/554D?
The UART can handle serial data rates up to 5 Mbit/s at 5 V and 3.3 V.
Does the SC16C554/554D support Infrared communication?
Yes, it provides an Infrared (IrDA) encoder/decoder interface.
Which IRQ numbers can be selected for the UART channels on the ISA bus?
The hardware allows selection of IRQ3, IRQ4, IRQ5, IRQ6, or IRQ7 via jumpers JP2‑JP5.

How do you enable a UART channel on the ISA interface?
A channel is enabled by installing a jumper on JP1; without the jumper the channel stays disabled by pull‑up resistors R1‑R4.
