The LX5204 is a nine-line active terminator
for the SCSI parallel bus. This SCSI standard
recommends active termination at both
ends of the SCSI bus. The LX5204 has the
added features of hot swappability, fully
complying with the SCSI hot swap speci-
fication.
quires a meager 60µA of supply current while
offering only 3.5pF of output capacitance.
To enter this low-power mode, the discon-
nect pin can be left open (floating) or driven
high, thereby disconnecting the terminating
resistors and placing the internal low dropout
regulator into low-power mode. In discon-
nect 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.

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
