UCC5620 27-Line SCSI Terminator FEATURES DESCRIPTION • Complies with SCSI, SCSI-2, SCSI-3, UCC5620 provides 27 lines of active termination for a SCSI (Small Com- SPIand FAST-20 (Ultra) Standards puter Systems Interface) parallel bus. The SCSI standard recommends active termination at both ends of the cable. • 2.5pF Channel Capacitance during Disconnect The UCC5620 is ideal for high performance 5V SCSI systems. During disconnectthesupplycurrentistypicallyonly100µA,whichmakestheIC • 100mA Supply Current in Disconnect attractive for lower powered systems.
