Notes:

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.
6. These inputs are normally wired to V
CC
, GND, or left unconnected (actual threshold voltages vary as a percentage of V
CC
). Internal termination resistors hold
the unconnected inputs at V
CC
/2. If these inputs are switched, the function and timing of the outputs may glitch and the PLL may require an additional t

time
before all data sheet limits are achieved.
