FEATURES:
0.5 MICRON CMOS Technology
Guaranteed low skew < 250ps (max.)
Very low duty cycle distortion < 350ps (max.)
High speed: propagation delay < 2.5ns (max.)
100MHz operation
TTL compatible inputs and outputs
TTL level output voltage swings
1:10 fanout
Output rise and fall time < 1.5ns (max)
Low input capacitance: 4.5pF typical
High drive: -32mA I
OH
, +48mA I
OL
Available in QSOP, SSOP, and SOIC packages
DESCRIPTION:
The FCT807T clock driver is built using advanced dual metal CMOS
technology. This low skew clock driver features 1:10 fanout, providing
minimal loading on the preceding drivers. The FCT807T offers low
capacitance inputs with hysteresis for improved noise margins. TTL level
outputs and multiple power and grounds reduce noise. The device also
features -32/48mA drive capability for driving low impedance traces.
