Power Supply Sequencing
ommends that the 1.8 V power supply be energized
before the 3.3 V supply. If this is not possible, the 1.8 V
supply may not lag the 3.3 V supply by more than 100
µs. If longer delay time is needed, it is recommended
that the voltage difference between the two power sup-
plies be within 1.5 V during power supply ramp up. To
avoid a potential latchup condition, voltage should be
applied to input pins only after the device is powered-
on as described above.
