PIN DESCRIPTIONS
DIFFB:
DIFF SENSE filter pin should be connected to a
0.1
μ
F capacitor to GND and 20k resistor to SCSI/Bus
DIFF SENSE Line.
DIFFSENS:
The SCSI bus DIFF SENSE line is driven to
1.3V to detect what type of devices are connected to the
SCSI bus.
HS/GND:
Heat Sink GND. Connect to large area PC
board traces to increase power dissipation capability.
GND:
Power Supply Return.
L1– thru L9–:
Signal line/active line for single ended or
negative line in differential applications for the SCSI bus.
L1+ thru L9+:
Ground line for single ended or positive
line for differential applications for the SCSI bus.
MSTR/SLV:
Mode select for the non-controlling termina-
tor. MSTR enables the 1.3V regulator, when the termina-
tor is enabled.
Note:
This function will be removed on
further generations of the multimode terminators.
REG:
Regulator bypass, must be connected to a 4.7
μ
F
capacitor.
TRMPWR:
V
IN
3.0V to 5.25V supply.
