3.3V CMOS
1-TO-10 CLOCK DRIVER
DESCRIPTION:
The FCT3807/A 3.3V clock driver is built using advanced dual metal CMOS
technology. This low skew clock driver offers 1:10 fanout. The large fanout from
a single input reduces loading on the preceding driver and provides an efficient
clock distribution network. The FCT3807/A offers low capacitance inputs with
hysteresis for improved noise margins. Multiple power and grounds reduce
noise. Typical applications are clock and signal distribution.

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 = 3.3V, +25°C ambient.
3. Per TTL driven input (VIN = VCC -0.6V); 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 + ΔICC DHNT + ICCD (fi)
ICC = Quiescent Current (ICCL, ICCH and ICCZ)
ΔICC = Power Supply Current for a TTL High Input (VIN = VCC -0.6V)
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)
fi = Input Frequency
All currents are in milliamps and all frequencies are in megahertz.
