3.3V CMOS 1-TO-10 CLOCK DRIVER COMMERCIAL/INDUSTRIAL TEMPERATURE RANGES

3.3V CMOS IDT74FCT3807/A

1-TO-10 CLOCK DRIVER

FEATURES: DESCRIPTION:
0.5 MICRON CMOS Technology The FCT3807/A 3.3V clock driver is built using advanced dual metal CMOS
Guaranteed low skew < 350ps (max.) technology. This low skew clock driver offers 1:10 fanout. The large fanout from
Very low duty cycle distortion < 350ps (max.) a single input reduces loading on the preceding driver and provides an efficient
High speed: propagation delay < 3ns (max.) clock distribution network. The FCT3807/A offers low capacitance inputs with
Very low CMOS power levels hysteresis for improved noise margins. Multiple power and grounds reduce
TTL compatible inputs and outputs noise. Typical applications are clock and signal distribution.
1:10 fanout
Maximum output rise and fall time < 1.5ns (max.)
Low input capacitance: 4.5pF typical
VCC = 3.3V 0.3V
Inputs can be driven from 3.3V or 5V components
Available in SSOP, SOIC, and QSOP packages
