UCC5631AFQP

Overview

The UCC5631AFQP is a multimode SCSI 9-line terminator manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.25 V and supports Ultra320 SCSI standards. The device features a 48-LQFP package and includes reverse disconnect functionality for bus protection. It is designed for high-speed data transmission with a typical propagation delay of 11 ns and a maximum data rate of 100 Mb/s per channel in related isolation contexts, though primarily functioning as a terminator.

Feature Summary

Supports multimode SCSI 9-line termination for Ultra320 compatibility
Integrates reverse disconnect protection mechanisms
Operates across wide voltage ranges from 2.7 V to 5.25 V

Applications

SCSI bus termination in server architectures
High-speed peripheral interface circuits
Ultra320 SCSI system integration

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and pin alignment upon receipt. Check for moisture sensitivity labels if storage conditions were not strictly controlled. Ensure the part number matches the specific LQFP-48 variant required for your design.

Selection Notes

Select this component when designing SCSI interfaces requiring robust termination and reverse polarity protection. Consider the 48-LQFP footprint for PCB layout constraints. Evaluate thermal dissipation requirements given the power consumption characteristics. Ensure compatibility with 3V to 5V logic levels used in legacy and modern SCSI systems.

Part Context

Part of the UCC5631A series, focusing on SCSI interface solutions. Designed to replace older discrete termination networks. Offers integrated protection features reducing external component count. Targets industrial and enterprise storage applications requiring reliable data link termination.

Replacement Considerations

UCC5631MWP is a similar SSOP-36 packaged variant. Verify pinout compatibility before substitution. Check voltage tolerance differences between packages. Ensure mechanical fit within existing enclosure constraints.
