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.

3.3V CMOS 1-TO-10 CLOCK DRIVER

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.
