LOW SKEW, 1-TO-4
LVCMOS / LVTTL INVERTING FANOUT BUFFER
GENERAL DESCRIPTION
FEATURES
The ICS8304-01 is a low skew, 1-to-4 Invert- • 4 LVCMOS / LVTTL outputs
,&6
ing Fanout Bufferand 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,
• Output frequency up to 166MHz
HiPerClockS™
• LVCMOS clock input
• 3.3V input, outputs may be either 3.3V or 2.5V supply modes
• Small 8 lead SOIC package saves board space
• 0°C to 70°C ambient operating temperature
• Industrial temperature version available upon request
and mixed 3.3V and 2.5V for output operating supply
modes (VDDO). Guaranteed output and part-to-part
skew characteristics make the ICS8304-01 ideal for
those clock distribution applications demanding well
defined performance and repeatability.

All parameters measured at 166MHz unless noted otherwise.
NOTE 1: Measured from the differential input crossing point to the differential output crossing point.
NOTE 2: Defined as skew between outputs at the same supply voltage and with equal load conditions.
Measured at the output differential cross points.
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 the differential cross points.
NOTE 4: Measured by triggering on input signal and measuring the largest displacement between output cycles.
