DESCRIPTION
Termination Power. Should be connected
to the SCSI TERMPWR line. A 10µF
tantalum local bypass capacitor is
recommended per system, as shown in
the application diagram

DESCRIPTION
2.85VREF Output. External decoupling
with a 10µF tantalum in parallel with a
0.1µF ceramic capacitor is
recommended, as shown in the
application diagram.
Disconnect Terminator. Logic input to
disconnect the terminator from the bus
when the SCSI device no longer needs
termination due to not being the last
device on the bus or otherwise. Active
low input.
Ground. Signal ground (0V)
Heat Sink Ground. Should be
connected to GND.
NOTE : The DISCNKT line has a 200kΩ internal pullup resistor connected to the
supply. This pin should be left floating for normal operation and should
be connected to ground to enable the function.
