Product Description
Pericom Semiconductors PI49FCT series of logic circuits are
produced using the Companys advanced 0.8 micron CMOS
technology, achieving industry leading speed grades.
The PI49FCT807T and PI49FCT2807T clock drivers feature one
input and ten outputs. The large fanout from a single input line
reduces loading on input clock. TTL level outputs reduce noise
levels on the part. Typical applications are clock and signal
distribution.
The PI49FCT2807T also features a 25-ohm on-chip resistor for
lower noise.
