Recommended Operating Supply Voltages
Power-Up Sequence
PES24NT3, the power-up sequence must be as follows:
are avoided. There are no maximum time limitations in ramping to valid power levels. The power-down sequence must be in the reverse order of the
power-up sequence.
IDT 89HPES24NT3 Data Sheet
This section describes the sequence in which various voltages must be applied to the part during power-up to ensure proper functionality. For the
1. V
2. V
3. V
When powering up, each voltage level must ramp and stabilize prior to applying the next voltage in the sequence to ensure internal latch-up issues
