This device contains circuitry to protect the inputs against
damage due to HIGH static voltages or electric field. However,
precautions should be take to avoid application of any voltage
higher than the maximum rated voltages to this circuit. For
proper operation, V
IN
and V
OUT
should be constrained to the
range.

Unused inputs must always be tied to an appropriate logic
voltage level (either V

Multiple Supplies:
The Voltage on any input or I/O pin cannot exceed the power pin during power-up. Power supply sequencing is NOT required.
All outputs loaded as per maximum capacitative load table in P4 and DDR mode.
See
Table 11
.
All outputs loaded as per loading specified in the loading table. See
Table 11
.
This measurement is applicable with Spread ON or spread OFF.
This is required for the duty cycle on the REF clock out to be as specified. The device will operate reliably with input duty cycles up to 30/70 but the REF clock
duty cycle will not be within data sheet specifications.
The typical value of VX is expected to be 0.5*VDDD (or 0.5*VDDC for CPUCS signals) and will track the variations in the DC level of the same.
Measured between 0.2Vdd and 0.7Vdd.

between 20% and 80% for differential signals.

Probes are placed on the pins, and measurements are acquired at 2.4V for 3.3V signals and at 2.0V for 2.5V signals.
