UCC5622MWPTR FEATURES


• Complies with SCSI, SCSI-2, SCSI-3,SPI and FAST-20 (Ultra) Standards

UCC5622MWPTR DESCRIPTION

The UCC5622 provides 27 lines of active termination for a SCSI (SmallComputer Systems Interface) parallel bus. The SCSI standard recom-mends active termination at both ends of the cable.
• 2.5pF Channel Capacitance DuringDisconnect
• 100 A Supply Current in DisconnectMode
• 4V To 7V Operation
• 110 Termination
• Completely Meets SCSI Hot Plugging
• –900mA Sourcing Current forTermination
• +500mA Sinking Current for ActiveNegation
• Logic Command Disconnects allTermination Lines
• Split Disconnect Controls Lines 1 to 9and 10 to 27 Separately
• Trimmed Impedance to 5%
• Current Limit and Thermal ShutdownProtection

UCC5622MWPTR PIN DESCRIPTIONS

DISCNCT1: Disconnect one controls termination lines10 – 27. Taking this pin high or leaving it open causestermination lines 10 - 27 to become high impedance, tak-ing this pin low allows the channels to provide normal ter-mination.DISCNCT2: Disconnecttwo controls termination lines1 – 9. Taking this pin high or leaving it open causestermination lines 1 - 9 to become high impedance. Takingthis pin low allows the channels to provide normaltermination. Taking both disconnect pins high or leavingthem open will put the chip in to sleep mode where it willbe in low-power mode.GND: Ground reference for the IC.L1 – L27: 110 termination channels.REG: Output of the internal 2.7V regulator.TRMPWR: Power for the IC.Figure 1.Typical Wide SCSI Bus Configuration Using the UCC56223
