UCC5606PWPTR Datasheet

SCSI Interface IC


The UCC5606PWPTR provides 9 lines of active termination for a SCSI (Small Computer Systems Interface) parallel bus. The SCSI standard recommends active termination at both ends of the cable segment.The UCC5606PWPTR is ideal for high performance 3.3V SCSI systems. The key features contributing to such low operating voltage are the 0.1V drop out regulator and the 2.7V reference. The reduced reference voltage was necessary to accommodate the lower termination current dictated in the SCSI-3 specification. During disconnect the supply current is typically only 1mA, which makes the IC attractive for battery powered systems. UCC5606PWPTR Features • Complies with SCSI, SCSI-2 and SCSI-3 Standards• 2.7V to 7V Operation• 1.8pF Channel Capacitance during Disconnect• 1mA Supply Current in Disconnect Mode• 110 Ohm/2.5k Programmable Termination• Completely Meets SCSI Hot Plugging• -400mA Sourcing Current for Termination• +400mA Sinking Current for Active Negation Drivers• Trimmed Termination Current to 4%• Trimmed Impedance to 7%• Current Limit and Thermal Shutdown Protection
