DISCNKT
Terminator disconnect. Logic
input to disconnect the
terminator from the bus when
the SCSI device no longer
needs termination.
DISCNKT
has a 200k�½ internal pull-up
resistor connected to
TERMPWR for use with a
mechanical switch
20, 21 TERMPWR Power should be connected
to the SCSI TERMPWR line.
A 22µF tantalum bypass
capacitor is recommended
as shown in the application
diagram

output. External
decoupling with a 10µF
tantalum in parallel with a
0.1µF ceramic capacitor is
recommended as shown in the
application diagram
