Preliminary Information

PSD4000 Series

NOTE: 1. Reset input has hysteresis. VIL1 is valid at or below .2VCC –.1. VIH1 is valid at or above .8VCC.

2. CSI deselected or internal Power Down mode is active.

3. PLD is in non-turbo mode and none of the inputs are switching

4. Refer to Figure 32 for PLD current calculation.

5. IO = 0 mA
