1 IDT49FCT806/A FAST CMOS BUFFER/CLOCK DRIVER COMMERCIAL TEMPERATURE RANGE SEPT. 2009 2006 Integrated Device Technology, Inc. DSC-5837/3c IDT49FCT806/A COMMERCIAL TEMPERATURE RANGE FAST CMOS BUFFER/CLOCK DRIVER FUNCTIONAL BLOCK DIAGRAM FEATURES: • 0.5 MICRON CMOS Technology • Guaranteed low skew < 700ps (max.) • Low duty cycle distortion < 1ns (max.) • Low CMOS power levels • TTL compatible inputs and outputs • Rail-to-rail output voltage swing • High drive: -24mA IOH, +64mA IOL • Two independent output banks with 3-state control • 1:5 fanout per bank • "Heartbeat" monitor output • Available in SSOP and SOIC packages NOTE: EOL for non-green parts to occur on 5/13/10 per PDN U-09-01 The IDT logo is a registered trademark of Integrated Device Technology, Inc. DESCRIPTION: 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. INA INB OEB OEA OA1-OA5 OB1-OB5 MON 5 5

I have always get a fast response from Heisener with my orders. As a small business owner I greatly appreciate that I can order as little as 1 item as opposed to other companies who require you place a larger minimum order.


August 17, 2020

A convenient and small package. I have used 2 of the 10 units so far and they work fine.


August 11, 2020

Item sent as described. Showed up quickly. Worked as it said and would recommend again.


August 9, 2020

Great product & fast shipping. Works as they should.


August 8, 2020
