ICS8304
LOW SKEW, 1-TO-4
LVCMOS / LVTTL FANOUT BUFFER
GENERAL DESCRIPTION
The ICS8304 is a low skew, 1-to-4 Fanout
ICS Buffer and a member of the HiPerClockS ™
HiPerClockS™ family of High Perfor mance Clock Solutions
from ICS. The ICS8304 is characterized at
full 3.3V for input V , and mixed 3.3V and 2.5V
DD
for output operating supply modes (VDDO). Guaranteed out-
put and part-to-part skew characteristics make the
ICS8304 ideal for those clock distribution applications
demanding well defined performance and repeatability.
FEATURES
• 4 LVCMOS / LVTTL outputs
• LVCMOS / LVTTL clock input
• Maximum output frequency: 200MHz
• Output skew: 45ps (maximum at 3.3V supply)
• Part-to-part skew: 500ps (maximum)
• Small 8 lead SOIC package saves board space
• 3.3V input, outputs may be either 3.3V or 2.5V supply modes
• Lead-Free package available
• 0°C to 70°C ambient operating temperature
