UCC5519PWP

Overview

The UCC5519PWP is a multi-mode SCSI terminator manufactured by Texas Instruments, designed for high-speed data bus applications. It operates within a supply voltage range of 2.7 V to 5.5 V and features an adjustable termination voltage. The device supports multiple termination modes including active, passive, and power-down states to optimize signal integrity and power consumption. Packaged in a 28-pin TSSOP (PW) format, it is rated for industrial temperature operation from -40°C to +85°C. Key electrical parameters include a quiescent current of 3 mA and a shutdown current of less than 1 µA, ensuring efficient performance in server and storage systems.

Feature Summary

• Supports multiple termination modes including active, passive, and power-down configurations for flexible system integration.

Applications

• SCSI bus termination in server environments
• High-speed data interface protection
• Storage area network (SAN) components

Procurement Notes

Verify the specific suffix 'PWP' corresponds to the 28-TSSOP package and industrial temperature grade. Confirm RoHS compliance status through official documentation as requirements may vary by production batch. Ensure compatibility with existing board layout constraints regarding the surface-mount footprint.

Selection Notes

Select this component when designing systems requiring robust SCSI termination with low standby power consumption. Consider the 28-pin TSSOP package size for space-constrained PCB layouts. Verify that the operating voltage range aligns with the system's power supply rails before finalizing the design.
