Product Summary
The UCC5617DWP is an 18 lines of active terminator for a SCSI (Small Computers Systems Interface) parallel bus. The SCSI standard recommends and Fast-20 (Ultra) requires active termination at both ends of the cable. Pin for pin compatible with the UC5609, the UCC5617DWP is ideal for high performance 5V SCSI systems, Termpwr 4.0V to 5.25V. During disconnect the supply current is only 50mA typical, which makes the IC attractive for lower powered systems. The UCC5617DWP is designed with a low channel capacitance of 2pF, which eliminates effects on signal integrity from disconnected terminators at interim
points on the bus.
