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 (VDDO). Guaran-
teed output and part-to-part skew characteristics make
the ICS8304I ideal for those clock distribution
www.DataSheeat4pUp.cliocmations 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

All parameters measured at 166MHz unless noted otherwise.
NOTE 1: Measured from VDD/2 of the input to VDDO/2 of the output.
NOTE 2: Defined as skew between outputs at the same supply voltage and with equal load conditions.
Measured at VDDO/2.
NOTE 3: Defined as skew between outputs on different devices operating at the same supply voltages
and with equal load conditions. Using the same type of inputs on each device, the outputs are measured
at V /2.
DDO
NOTE 4: This parameter is defined in accordance with JEDEC Standard 65.
