### **Descriptions:**  
The SC16C554DBIA68 is a quad UART IC designed for high-performance serial communication. It integrates four independent UART channels, each with 64-byte FIFOs to reduce CPU overhead. It supports flexible baud rate generation and is compatible with 3.3V and 5V systems.  

### **Features:**  
- Four independent UART channels  
- 64-byte transmit and receive FIFOs per channel  
- Programmable baud rate generator (up to 5 Mbps)  
- Supports 5V and 3.3V operation  
- Hardware and software flow control  
- Modem control signals (CTS, RTS, DSR, DTR, RI, DCD)  
- Infrared (IrDA) encoder/decoder support  
- Sleep mode for power savings  
- Industrial temperature range (-40°C to +85°C)  
- PLCC-68 package

Application Scenarios & Design Considerations

SC16C554B/554DB; 5 V, 3.3 V and 2.5 V quad UART, 5 Mbit/s (max.) with 16-byte FIFOs

Alternative Part Number

  • ST16C554DCJ68 --: Quad UART with 16-byte FIFOs in a 68-pin PLCC, functionally equivalent to the SC16C554 and a common drop-in replacement.
  • XR16C854CJ-F --: Quad UART with larger 128-byte FIFOs in a 68-pin PLCC, pin-compatible upgrade path for the SC16C554DB.
  • TL16C554AIPN --: Quad asynchronous communications element with 16-byte FIFOs, widely available alternative with similar register set and interface.
  • ST16C554DIQ64 --: Pin-compatible quad UART from MaxLinear (formerly Exar) with similar 16C554 register set and functionality, widely used as a drop-in replacement for NXP SC16C554 devices.
  • XR16C854DIV --: Quad UART with 128-byte FIFOs and enhanced features that supersedes the 16C554 family; offers higher performance and is a common upgrade path when the SC16C554 is unavailable.
