Pin Characteristics
IDT 89HPES8T5 Data Sheet
Note: Some input pads of the PES8T5 do not contain internal pull-ups or pull-downs. Unused 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 input pin left
floating can cause a slight increase in power consumption.
