ICS8302I-01 LOW SKEW, 1-TO-2 LVCMOS / LVTTL FANOUT BUFFER W/ COMPLEMENTARY OUTPUT GENERAL DESCRIPTION The ICS8302I-01 is a low skew, 1-to-2 LVCMOS/LVTTL Fanout Buffer w/Complemen- tary Output and a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. The ICS8302I-01 has a single ended clock input. The single ended clock input accepts LVCMOS or LVTTL input levels. The ICS8302I-01 is characterized at full 3.3V for input VDD, and mixed 3.3V and 2.5V for output operating supply modes (VDDO). Guaranteed output and part-to-part skew characteristics make the ICS8302I-01 ideal for clock distribution applications demanding well defined performance and repeatability.
