PIN DESCRIPTION
DIFFB:
Differential sense filter pin should be connected
to a 0.1
μ
F capacitor and 20k
resistor to Diff Sense.
DIFSENS:
The SCSI bus differential sense line to detect
what type of devices are connected to the SCSI Bus.
DISCNCT:
Disconnect pin shuts down the terminator
when it is not at the end of the bus.
GND:
Ground.
Ln –:
Negative line in differential applications for the
SCSI Bus.
Ln +:
Positive line for differential applications for the
SCSI Bus.
LVD:
(28 pin package only) Indicates that the bus is in
LVD mode.
REG:
Regulator bypass; must be connected to a 4.7 F
capacitor to ground.
TRMPWR:
V
IN
2.7V to 5.25V supply.
