DESCRIPTION
●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 µA, which makes the device attractive for battery powered systems
