ESCRIPTION
The ICS8343 is a low skew, 1-to-16 Fanout
Buffer and a member of the HiPerClockS
family of High Performance Clock Solutions
from ICS. The ICS8343 is at 3.3V, 2.5V and
mixed 3.3V input and 2.5V supply modes over
the commercial temperature range. Guaranteed output and
part-to-part skew characteristics make the ICS8343 ideal for
those clock distribution applications demanding well defined
performance and repeatability.
