UC5608DWP

Overview

The UC5608DWP is an 18-line low capacitance SCSI active terminator manufactured by Texas Instruments. It is designed to terminate SCSI bus lines, providing signal integrity for high-speed data transmission. The device operates within a standard industrial temperature range and utilizes a TSSOP-24 package. Key electrical characteristics include a supply voltage range of 4.75V to 5.25V and a typical quiescent current of 30mA per channel. The component features low output impedance and fast switching speeds to minimize signal reflections on the SCSI bus.

Feature Summary

• Integrates 18 termination channels for comprehensive SCSI bus coverage
• Low capacitance design to preserve signal integrity at high frequencies
• Active termination capability reduces power consumption compared to passive methods

Applications

• SCSI host adapter termination
• Peripheral device bus termination
• High-speed digital interface signal conditioning

Procurement Notes

Verify the specific suffix DWP indicates the TSSOP-24 package variant when sourcing. Confirm RoHS compliance status with the supplier as manufacturing processes may vary. Ensure the vendor provides original manufacturer documentation to validate authenticity. Check for any recent product lifecycle notices regarding obsolescence or replacement recommendations before finalizing procurement plans.

Selection Notes

Select this component for systems requiring precise termination of 18 SCSI lines. Compare against similar models like UC5604 or UC5609 if fewer lines are needed. Consider thermal performance in enclosed designs due to active termination power dissipation. Verify compatibility with the specific SCSI speed standards supported by the target application architecture.

Part Context

The UC5608 belongs to Texas Instruments' family of SCSI active terminators. It complements other devices such as the UC5604 and UC5605 which offer different line counts. This series addresses the need for reliable signal termination in legacy and specialized storage interfaces. The DWP suffix specifically denotes the thin-shrink small-outline package suitable for space-constrained PCB layouts.

Replacement Considerations

UC5608DWPTR is the tape-and-reel version of the same functional device. UC5609 offers identical 18-line functionality but may differ in package or revision. Verify pinout compatibility before substituting with related SCSI terminator parts.
