INDUSTRIAL TEMPERATURE RANGE
3.3V CMOS
1-TO-2 CLOCK DRIVER
DESCRIPTION:
The FCT38072 is a 3.3V clock driver built using advanced CMOS
technology. This low skew clock driver offers 1:2 fanout. The large fanout from
a single input reduces loading on the preceding driver and provides an efficient
clock distribution network. Multiple power and grounds reduce noise. Typical
applications are clock and signal distribution.
