1.75V Regulated Output. Capable of sourcing/sinking 200mA.
0.75V Regulated Output. Capable of sourcing/sinking 200mA.
Power supply pin for terminator. Connect to SCSI bus VTERM. Usually decoupled
by one 4.7
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.
1.3V buffered output for DIFSENS signaling.
Regulator ground pin. Connect to ground.
Attached to die mounting pad, but not bonded to GND pin. Pins should be considered a
heat sink only, and not a true ground connection. It is recommended that these pins be
connected to ground, but can be left floating.
