DESCRIPTION:
non-inverting clock buffer. The large fanout from a single input reduces loading
on the preceding driver and provides an efficient clock distribution network.
Providing output to output skew as low as 150ps, the FCT20807 is an ideal clock
distribution device for synchronous systems. Multiple power and grounds
reduce noise. Typical applications are clock and signal distribution.
PIN CONFIGURATION
The FCT20807 is a 2.5V compatible, high speed, low noise, 1:10 fanout,
