IDT49FCT805BT/CT FAST CMOS BUFFER/CLOCK DRIVER MILITARY AND COMMERCIAL TEMPERATURE RANGES FAST CMOS IDT49FCT805BT/CT BUFFER/CLOCK DRIVER FEATURES: DESCRIPTION: 0.5 MICRON CMOS Technology This buffer/clock driver is built using advanced dual metal CMOS Guaranteed low skew < 500ps (max.) technology. The FCT805T is a non-inverting clock driver consisting of two Very low duty cycle distortion < 600ps (max.) banks of drivers. Each bank drives five output buffers from a standard TTL Low CMOS power levels compatible input. This part has extremely low output skew, pulse skew, and TTL compatible inputs and outputs package skew. The device has a heart-beat monitor for diagnostics and TTL level output voltage swings PLL driving. The monitor output is identical to all other outputs and complies High drive: -32mA IOH, +48mA IOL with the output specifications in this document. Two independent output banks with 3-state control The FCT805T is designed for fast, clean edge rates to provide accurate 1:5 fanout per bank clock distribution in high speed systems. Heartbea monitor output ESD > 2000V per MIL-STD-883, Method 3015 > 200V using machine model (C = 200pF, R = 0) Available in the following packages: Commercial: QSOP, SOIC, SSOP Military: CERDIP, LCC FUNCTIONAL BLOCK DIAGRAM OEA 5 INA OA1-OA5 5 INB OB1-OB5 OEB MON The IDT logo is a registered trademark of Integrated Device Technology, Inc.
