ESCRIPTION
The ICS8343-01 is a low skew, 1-to-16 LVCMOS/
LVTTL Fanout Buffer and a member of the
HiPerClockS™
HiPerClockS™ family of High Performance Clock
Solutions from ICS. The ICS8343-01 single ended
clock input accepts LVCMOS or LVTTL input levels.
The ICS8343-01 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 ICS8343-01 ideal for those clock distribution applications
demanding well defined performance and repeatability.
