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.

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.
