DESCRIPTION  
KEY FEATURES  
3.0pF OUTPUT CAPACITANCE DURING  
The LX5107 is a nine-line active terminator  
for the SCSI parallel bus. This SCSI stan-  
dard recommends active termination at  
both ends of the SCSI bus.  
the lowest enabled supply current of any  
terminator available on the market today.  
Linfinity's proprietary BiCMOS low drop-  
out regulator architecture enables this  
unique and very efficient operating char-  
acteristic.  
The LX5107 also offers a precisely  
trimmed channel output current specified  
to a 5% tolerance. The maximum value  
of the output current is trimmed as closely  
as possible to the SCSI standard maximum  
specification to give the highest possible  
noise margin for fast SCSI operation. In  
addition, the LX5107 sinks up to 50mA of  
current making it compatible with today's  
fast active negation drivers.  
DISCONNECT  
30µA SUPPLY CURRENT IN DISCONNECT  
MODE  
During disconnect mode, the LX5107  
requires a meager 30µA of supply current  
while offering only 3.0pF of output capaci-  
tance. To enter this low-power mode, the  
disconnect pin should be driven low  
thereby disconnecting the terminating re-  
sistors and placing the internal low drop-  
out regulator into low-power mode. In  
disconnect mode, each termination line  
presents a high impedance to the SCSI bus  
with the overall effect being to preserve  
high signal integrity and yield subsequent  
reliable, error free communications.  
During normal operation, the LX5107  
consumes only 600µA of current which is  
600µA SUPPLY CURRENT DURING NORMAL
