Pin Characteristics
IDT 89HPES48H12G2 Data Sheet
Note: Some input pads of the switch do not contain internal pull-ups or pull-downs. Unused SMBus and System inputs should be tied off to
appropriate levels. This is especially critical for unused control signal inputs which, if left floating, could adversely affect operation. Also, any
of these pins left floating can cause a slight increase in power consumption. Finally, unused Serdes (Rx and Tx) pins should be left floating.
