The 49FCT5805 clock buffer/driver circuits can be used for clock

bufferingschemes where lowskewis a keyparameter.This device offers

twobanks offive non-invertingoutputs.The 49FCT5805device provides

low propagation delay buffering with on-chip skew of 0.3ns for same-

transition,same-banksignals.

Guaranteed low skew:

The 49FCT5805 is characterized for operation at -40°C to +85°C.
