Features, Applications

0.5 MICRON CMOS Technology Guaranteed low skew < 500ps (max.) Very low duty cycle distortion < 600ps (max.) Low CMOS power levels TTL compatible inputs and outputs TTL level output voltage swings High drive: -32mA IOH, +48mA IOL Two independent output banks with 3-state control 1:5 fanout per bank "Heartbeat" monitor output ESD > 2000V per MIL-STD-883, Method > 200V using machine model = 0) Available in the following packages: � Commercial: QSOP, SOIC, SSOP � Military: CERDIP, LCC

This buffer/clock driver is built using advanced dual metal CMOS technology. The is an inverting clock driver consisting of two banks of drivers. Each bank drives five TTL output buffers from a standard TTL compatible input. This part has extremely low output skew, pulse skew, and package skew. The device has a "heart-beat" monitor for diagnostics and PLL driving. The monitor output is identical to all other outputs and complies with the output specifications in this document. The FCT806T is designed for fast, clean edge rates to provide accurate clock distribution in high speed systems.
