PIN DESCRIPTION

Pin

Name

Function

1

REG

SCSI Regulator Output. Connect a 4.7-mF bypass capacitor from this pin to GND.

2, 3

N/C

No Connect.

4, 6, 11, 13,15, 22,

24, 29, 31

TXP; X = 1...9

Positive Terminator Channel Pins. Provide positive signal line termination in LVD operation, and are connected to

GND through low impedance in S/E operation. In HPD, DISABLE, or Power Off condition these pins present high

impedance to the SCSI Bus.

5, 7, 12, 14, 16, 23,

25, 30, 32

TXN; X = 1...9

Negative Terminator Channel Pins. Provide negative signal line termination in LVD operation, and line termination for

S/E operation. In HPD, DISABLE, or Power Off condition these pins present high impedance to the SCSI Bus.

8, 9, 10, 26, 27, 28

H/S GND

Heat Sink Ground. Should be connected to as large a grounded heat sink area on the PC board as is practical.

17

DISABLE

Chip Disable. There is a small (nominal 10 mA) pull up current on this pin. Pull this pin to GND to enable Bus

Termination. When this pin is left floating or pulled high all SCSI channel pins present high impedance to the SCSI

Bus, and the SCSI Regulator and DIFFSENS regulator are both disabled.

18

GND

Electrical ground connection for the terminator IC. Connect to the ground lines of the SCSI Bus

19

MSTR/SLV

Master/Slave. If this pin is tied to TERMPWR the output of the 1.3-V regulator for DIFFSENS is enabled. If this pin is

tied to GND the output of the 1.3-V regulator for DIFFSENS is inhibited.

20

DIFFS

DIFFSENS Regulator Output. Connect to the DIFFSENS line of the SCSI Bus to bias the mode selection function.

21

MODE

SCSI MODE Select Pin. Connect to the DIFFSENS line of the SCSI Bus to sense the present mode of operation on

the Bus. Decouple MODE from the DIFFSENS signal with a 50-kW/4.7mF low pass filter to meet SPI-3 mode change

requirements.

33, 34, 35

S/E, LVD, HPD

Status Output Pins. Respective pins are high when the terminator detects the corresponding mode of operation on

the SCSI Bus, and low otherwise.

36

TERMPWR

Power for the Terminator IC. Connect to the TERMPWR lines on the SCSI Bus and decouple with a 4.7-mF capacitor

to GND at the IC.
