• Guaranteed low skew < 700ps (max.)
• Low duty cycle distortion < 1ns (max.)
• Low CMOS power levels
TheFCT806isaninvertingbuffer/clockdriverbuiltusingadvanceddual
metalCMOStechnology. Eachbankconsistsoftwobanksofdrivers. Each
bankdrivesfiveoutputbuffersfromastandardTTLcompatibleinput. These
devicesfeaturea “heart-beat”monitorfordiagnosticsandPLLdriving. The
MON output is identical to all other outputs and complies with the output
specificationsinthisdocument.
• 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
The FCT806 offers low capacitance inputs and hysteresis. Rail-to-rail
outputswingimprovesnoisemarginandallowseasyinterfacewithCMOS

NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause
permanent damage to the device. This is a stress rating only and functional operation
of the device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.

NOTE:
1. This parameter is measured at characterization but not tested.
NOTE:
1. Pin 8 is not internally connected on devices with a "K" prefix in the date code. On older
devices, pin 8 is internally connected to GND. To insure compatibility with all products,
pin 8 should be connected to GND at the board level.

NOTES:
1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at Vcc = 5V, +25°C ambient.
3. Not more than one output should be shorted at one time. Duration of the test should not exceed one second.

NOTES:
1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at VCC = 5V, +25°C ambient.
3. Per TTL driven input (VIN = 3.4V); all other inputs at VCC or GND.
4. This parameter is not directly testable, but is derived for use in Total Power Supply calculations.
5. Values for these conditions are examples of the IC formula. These limits are guaranteed but not tested.
6. IC = IQUIESCENT + IINPUTS + IDYNAMIC
IC = ICC + ∆ICC DHNT + ICCD (fONO)
ICC = Quiescent Current (ICCL, ICCH and ICCZ)
∆ICC = Power Supply Current for a TTL High Input (VIN = 3.4V)
DH = Duty Cycle for TTL Inputs High
NT = Number of TTL Inputs at DH
ICCD = Dynamic Current Caused by an Input Transition Pair (HLH or LHL)
fO = Output Frequency
NO = Number of Outputs at fO
All currents are in milliamps and all frequencies are in megahertz.
