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 VDD, and
mixed 3.3V and 2.5V for output operating supply modes
(VDDO). 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
•4 LVCMOS / LVTTL outputs
•LVCMOS/LVTTL clock input
•Maximum output frequency: 166MHz
•Output skew: 50ps (maximum)
•Part-to-part skew: 600ps (maximum)
•Small 8 lead SOIC package saves board space
•3.3V input, outputs may be either 3.3V or 2.5V supply modes
•0°C to 70°C ambient operating temperature
•Lead-Free package fully RoHS compliant
