PIN DESCRIPTION
DIFFB: Differential sense filter pin should be connected
to a 0.1
µF 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.
L
n –: Negative line in differential applications for the
SCSI Bus.
L
n +: 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: VIN 2.7V to 5.25V supply.
