Product Description
Pericom Semiconductor聮s PI49FCT series of logic circuits are
produced using the Company聮s advanced 0.8 micron CMOS
technology, achieving industry leading speed grades.
The PI49FCT804T is a non-inverting clock driver designed with two
independent groups of buffers. These buffers have Hi-Z state
Output Enable inputs (active LOW) with a 1-in, 4-out configuration
per group. Each clock driver consists of two banks of drivers,
driving four outputs each from a standard TTL compatible CMOS
input.
