ESCRIPTION

The ICS8343I is a low skew, 1-to-16 Fanout

Buffer and a member of the HiPerClockS鈩?family

HiPerClockS鈩?/div>

of High Performance Clock Solutions from ICS.

The ICS8343I is at 5.0V, 3.3V, 2.5V and mixed

3.3V input and 2.5V supply modes over the com-

mercial temperature range. Guaranteed output and part-to-

part skew characteristics make the ICS8343I ideal for those

clock distribution applications demanding well defined per-

formance and repeatability.
