ProductDescription

Pericom Semiconductor’s PI49FCT series of logic circuits are

produced using the Company’s 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.
