UCC5606 具有反向关断功能的最低电容 9 线路 3-5V SE 端子，用于 SCSI 至 Ultra SCSI
The UCC5606 provides 9 lines of active termination for a small computer systems interface (SCSI) parallel bus. The SCSI standard recommends active termination at both ends of the cable segment.
The UCC5606 is ideal for high performance 3.3-V SCSI systems. The key features contributing to such low operating voltage are the 0.1-V drop out regulator and the 2.7-V reference. During disconnect the supply current is typically only 0.5 uA, which makes the device attractive for battery powered systems.
The UCC5606 is designed with an ultra-low channel capacitance of 1.8 pF, which eliminates effects on signal integrity from disconnected terminators at interim points on the bus.
The UCC5606 can be programmed for either a 110-
termination is connected when the DISCNCT\ pin is driven high, and disconnected when driven low
