active. This 3.3V input is level sensitive strobe used to
determine FS [4:0]. This pin is LOW active.
Power Down Function. This is power down pin, low active
(PD#).
Internal 120K pull up
Power good input signal is power on trapping with LOW
pairs. The pin was connected to the precision resistor
tied to ground to decide the appropriate current.
