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.

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.

consumes only 600µA of current which is

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

addition, the LX5107 sinks up to 50mA of

current making it compatible with today's

fast active negation drivers.
