Positive signal termination lines.
V
TERM
Power supply pin for terminator. Connect to SCSI bus TERMPWR. Must be decoupled by one 4.7μF
low-ESR capacitor for every three terminator devices. It is absolutely necessary to connect this pin to
the decoupling capacitor through a very low impedance (big traces on PCB). Keeping distances very
short from the decoupling capacitors to the V
pin is also critical. The value of the decoupling
capacitor is somewhat layout dependant and some applications may benefit from high-frequency
decoupling with 0.1μF capacitors right at V
TERM
pin.
Enables / disables terminator. See Power Down Function Table for logic levels per device.
DISC1
GND1
Terminator ground pin. Connect to ground.
DIFFSENSE1
Used to drive DIFFSENS output 3V @ 10 mt. Usually connected through a 20kOhm resistor to DIFF B
pin.
DIFFB1
Used to detect the SCSI BUS mode (LUD, HUD, SE)
