GENERAL DESCRIPTION
The ICS8304-01 is a low skew, 1-to-4 Invert-
ing Fanout Buffer and a member of the
HiPerClockS™ family of High Performance
Clock Solutions from ICS. The ICS8304-01
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 output and part-to-part skew char-
acteristics make the ICS8304-01 ideal for those clock
distribution applications demanding well defined per-
formance and repeatability.
FEATURES
