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.
