The UC5603 is an active terminator that complies with SCSI, SCSI-2, and SPI-2 standards. It provides 9 lines of termination and has a disconnect feature. It supports hot plugging and has current limit and thermal shutdown protection.
The UC5603 is a 9‑line SCSI active terminator that offers a disconnect feature to reduce standby power and maintain high‑impedance outputs when not powered. It includes internal trimming for impedance and output current to within 3% tolerance, and provides negative clamping, thermal shutdown, and current limiting for reliable operation.
The device is offered in several package types (SOIC‑16, PDIP‑16, PLCC‑28) and includes detailed electrical specifications such as 6 pF channel capacitance, ±400 mA source/sink capability, and a 170 °C thermal shutdown threshold. Ordering information, mechanical drawings, and packaging options are provided for design integration.
