TERM
Power supply pin for terminator. Connect to SCSI bus VTERM. Musts be
decoupled by one 4.7
μ
F 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 to PCB). Keeping distances very short from the decoupling
capacitors is somewhat layout dependent and some applications may benefit from high
frequency decoupling with 0.1

pin.
DISCONNECT
Enables/Disables terminator. See Power Down Function Table for logic levels
.
GND
Terminator ground pin. Connect to ground.
MASTER/SLAVE
Sometimes referred to as M/S pin in this datasheet. Used to select which terminator is the
controlling device. M/S pin High or Open enables the DIFFSENSE output drive. Please
see MASTER/SLAVE Function Table.
This is a dual function pin. It drives the SCSI bus DIFFSENS line. It is also the sense pin
to detect the SCSI bus mode (LVD, SE, or HVD). DIFFSENSE output drive can be
disabled with low level on the M/S pin. Please see DIFFSENSE and MASTER/SLAVE
Function Tables. Note: Must connect Diffsense signal to Diffsense pin of LX5251.
