GENERAL DESCRIPTION
FEATURES
The ICS8304-01 is a low skew, 1-to-4 Invert- • 4 LVCMOS / LVTTL outputs
ICS
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
• LVCMOS/LVTTL clock input
HiPerClockS™
• Maximum output frequency: 166MHz
• Output skew: 50ps (maximum)
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.
• 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
