Overview
The UC5603QP is a 9-line SCSI active terminator manufactured by Texas Instruments, designed for high-speed data bus termination. It operates within an extended industrial temperature range of -40°C to +125°C and supports supply voltages from 4.75V to 5.25V. The device features low output impedance and includes internal pull-up resistors to maintain signal integrity during inactive states. It is housed in a small outline package suitable for surface-mount applications, ensuring reliable performance in demanding automotive and industrial environments.
Feature Summary
- Provides active termination for 9-line SCSI interfaces to reduce signal reflections
- Operates reliably across the full extended industrial temperature range
- Integrates internal pull-up mechanisms for stable logic levels
Applications
- Automotive electronic control units requiring robust SCSI communication
- Industrial automation systems with harsh environmental conditions
- High-reliability data acquisition hardware
Procurement Notes
Verify the QP suffix indicates automotive qualification status against official NXP or TI documentation. Confirm the specific package variant matches your PCB footprint requirements. Ensure the supplier provides traceability certificates if required for your quality management system standards.
Selection Notes
Select this component when a dedicated active terminator is preferred over passive resistor networks for improved signal quality. Consider the operating voltage compatibility with your system's 5V logic rails. Evaluate the thermal performance requirements given the extended temperature rating and package thermal resistance characteristics.
Part Context
This part belongs to the UC5603 family of SCSI terminators. The 'QP' designation typically signifies automotive-grade reliability and extended temperature capabilities compared to standard commercial variants. It serves as a specialized interface component within broader peripheral controller ecosystems.
Replacement Considerations
The UC5604QP may serve as a replacement if lower capacitance is required. Verify pinout compatibility before substitution. Other generic active terminators may lack the specific automotive qualification or exact electrical characteristics.
