UCC5614 电容最低的 9 线路 3-5V SE 终端，用于 SCSI 至 Ultra SCSI
The UCC5614 provides 9 lines of active termination for a small computer system’s interface (SCSI) parallel bus. The SCSI standard recommends active termination at both ends of the cable segment.
The UCC5614 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 UCC5614 is designed with an ultra low channel capacitance of 1.8 pF, which eliminates effects on signal i cted terminators at interim points on the bus.
The UCC5614 can be programmed for either a 110
