LVCMOS/LVTTL Fanout Buffer w/Complemen-
tary Output and a member of the HiPerClockSTM
family of High Performance Clock Solutions
from ICS. The ICS8302-01 has a single ended
clock input. The single ended clock input accepts LVCMOS
or LVTTL input levels. The ICS8302-01 is characterized
at full 3.3V for input V
DD
, and mixed 3.3V and 2.5V for
o u t p u t o p e r a t i n g s u p p l y m o d e s (V
