SCSI bus termination – 9-line active terminator
The UCC5606PWPTR is a 9-line active SCSI terminator from Texas Instruments, designed to terminate the signal lines on a SCSI bus to prevent reflections and maintain signal integrity. Its supply range of 2.7V to 5.25V covers both 3.3V and 5V SCSI logic families, which is the primary fit criterion when selecting a terminator for a legacy or new SCSI interface. The 9-line count matches the standard narrow SCSI termination requirement.
Package details and thermal design
Housed in a 24-TSSOP package with an exposed pad, the UCC5606PWPTR requires a thermal land on the PCB for effective heat transfer. The supplier device package is 24-HTSSOP. Available in Tape & Reel (TR) or Cut Tape (CT) options, the TR version is suited for automated pick-and-place in volume production, while CT suits prototype or low-volume builds.
Lifecycle and sourcing posture
For BOM planning, no immediate LTB (last-time buy) risk exists. As an active TI part, the UCC5606PWPTR is available through distributor channels. Pricing and lead time are confirmed at the time of RFQ.
