ESCRIPTION
The ICS8343I-01 is a low skew, 1-to-16
LVCMOS/LVTTL Fanout Buffer and a member of
the
HiPerClockS family of High Performance
Clock Solutions from ICS. The ICS8343I-01
single ended clock input accepts LVCMOS or
LVTTL input levels. The ICS8343I-01 operates at 3.3V,
2.5V and mixed 3.3V input and 2.5V supply modes over the
commercial temperature range. Guaranteed output and part-
to-part skew characteristics make the ICS8343I-01 ideal for
those clock distribution applications demanding well defined
performance and repeatability.
