Product Description
Pericom Semiconductors PI49FCT series of logic circuits are
produced in the Companys 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.
