ICS8304I
LOW SKEW, 1-TO-4
LVCMOS / LVTTL FANOUT BUFFER
GENERAL DESCRIPTION
The ICS8304I is a low skew, 1-to-4 Fanout
,&6
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 , and mixed 3.3V and
DD
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.
FEATURES
• 4 LVCMOS / LVTTL outputs
• LVCMOS clock input
• CLK can accept the following input levels: LVCMOS, LVTTL
• Maximum output frequency: 166MHz
• Output skew: 60ps (maximum)
• Part-to-part skew: 650ps (maximum)
• Small 8 lead SOIC package saves board space
• 3.3V input, outputs may be either 3.3V or 2.5V supply modes
• -40°C to 85°C ambient operating temperature
