FEATURES  
DESCRIPTION  
D
Complies with SCSI, SCSI-2 and SPI-2  
Standards  
The UC5612 provides 9 lines of active termination for a  
small computer systems interface (SCSI) parallel bus.  
The SCSI standard recommends active termination at  
both ends of the cable segment.

5-pF Channel Capacitance During Disconnect

−400-mA Sourcing Current for Termination  
+100-mA Sinking Current for Active Negation  
1-V Dropout Voltage Regulator  
The only functional differences between the UC5603  
and UC5612 is the absence of the negative clamps on  
the output lines. Parametrically, the UC5612 has a 5%  
tolerance on impedance and current compared to a 3%  
tolerance on the UC5603. Custom power packages are  
utilized to allow normal operation at full power at 2 W.

100-µA Supply Current In Disconnect Mode  
Trimmed Termination Current to 5%  
Trimmed Impedance to 5%  
The UC5612 provides a disconnect feature which,  
when opened or driven high, disconnects all terminating  
resistors, disables the regulator and greatly reduces  
standby power consumption. The output channels  
remain high impedance even without TERMPWR  
applied. A low channel capacitance of 5 pF allows  
interim points of the bus to have little to no effect on the  
signal integrity.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam  
during storage or handling to prevent electrostatic damage to the MOS gates.
