ESCRIPTION
The ICS8304I 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 ICS8304I is characterized at
full 3.3V for input V
DD
, and mixed 3.3V and
2.5V for output operating supply modes (V
DDO
). Guaran-
teed output and part-to-part skew characteristics make
the ICS8304I ideal for those clock distribution
applications demanding well defined performance and
repeatability.
