ESCRIPTION
The ICS8304 is a low skew, 1-to-4 Fanout
Buffer and a member of the HiPerClockS
™
HiPerClockS™
family of High Performance Clock Solutions
from ICS. The ICS8304 is characterized at
full 3.3V for input V
DD
, and mixed 3.3V and 2.5V
for output operating supply modes (V
DDO
). Guaranteed out-
put and par t-to-par t skew character istics make the
ICS8304 ideal for those clock distribution applications
demanding well defined performance and repeatability.
