UCC5617 具有反向感应、电容最低的 18 线路 3-5V SE 终端,用于 SCSI 至 Ultra SCSI

The UCC5617 provides 18 lines of active termination 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 UCC5617 is ideal for high performance 5V SCSI systems, Termpwr 4.0-5.25V. During disconnect the supply current is only 50uA typical, which makes the IC attractive for lower powered systems.

The UCC5617 is designed with a low channel capacitance of 2pF, which eliminates effects on signal integrity from disconnected terminators at interim points on the bus.

The power amplifier output stage allows the UCC5617 to source full termination current and sink active negation current when all termination lines are actively negated
