The UC5601 is an active terminator that complies with SCSI and SCSI-2 standards. It has a channel capacitance of 10pF during disconnect and features low power consumption, logic command disconnect of termination lines, and accurate termination current.
The UC5601 is a precision SCSI‑2 active terminator that provides a 2.9 V pull‑up on all 18 bus lines, meeting SCSI hot‑plugging requirements. It includes a logic‑controlled disconnect feature that removes termination resistors and powers down the regulator to reduce standby consumption.
Key features include ±3 % termination current accuracy, negative clamping, 20 mA active sink capability, current limiting, thermal shutdown, and availability in SOIC‑28, PLCC‑28, and DIL‑24 packages. The datasheet provides absolute maximum ratings, recommended operating conditions, and detailed electrical parameters for designers.
