The FCT806 is an inverting buffer/clock driver built using advanced dual metal CMOS technology. Each bank consists of two banks of drivers. Each bank drives five output buffers from a standard TTL compatible input. These devices feature a "heart-beat" monitor for diagnostics and PLL driving. The MON output is identical to all other outputs and complies with the output specifications in this document. The FCT806 offers low capacitance inputs and hysteresis. Rail-to-rail output swing improves noise margin and allows easy interface with CMOS inputs.
