V
TERM
Power supply pin for terminator. Connect to SCSI bus TERMPWR. Must be decoupled by one 4.7F
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
TERM pin is also critical. The value of the decoupling
capacitor is somewhat layout dependant and some applications may benefit from high-frequency
decoupling with 0.1F capacitors right at V
TERM pin.
DISC
Enables / disables terminator. See Power Down Function Table for logic levels per device.
GND
Terminator ground pin. Connect to ground.
DIFFSENSE
Differential sense pin connected to system DIFFSENSE line.
DIFFB
Used to detect the SCSI BUS mode (LVD, HVD, SE). Should be connected to 4.7F to ground
