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 PI49FCT805T and PI49FCT2805T are non-inverting clock
drivers. The PI49FCT806T is an inverting clock driver designed with
two independent groups of buffers that have Hi-Z state Output
Enable inputs (active LOW) with a 1-in, 5-out configuration per
group. Each clock driver consists of two banks of drivers, driving
five outputs each from a standard TTL-compatible CMOS input.
The PI49FCT2805T also features a 25-ohm on-chip resistor for lower
noise.
