PI49FCT804T
Fast CMOS Buffer/Clock Driver
Product Features
Low output skew: 0.8ns Clock busing with Hi-Z state control TTL input and output levels, reducing problematic ground bounce High output drive, IOL = 64mA Extremely low static power (1mW, typ.) Hysteresis on all inputs Packages available: 16-pin 300 mil wide plastic SOIC (S) 16-pin 150 mil wide QSOP (Q)
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 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.
