1-TO-4 CLOCK DRIVER
INDUSTRIALTEMPERATURERANGE
IDT74FCT38074
FEATURES:
• Advanced CMOS Technology
• Guaranteed low skew < 100ps (max.)
• Very low duty cycle distortion< 250ps (max.)
• High speed propagation delay< 3ns (max.)
• Very low CMOS power levels
• TTL compatible inputs and outputs
• 1:4 fanout
• Maximum output rise and fall time < 1.5ns (max.)
• Low input capacitance: 3pF typical
• VCC = 3.3V ± 0.3V
• Inputs can be driven from 3.3V or 5V components
• Operating frequency up to 166MHz
• Available in SOIC package
DESCRIPTION:
The FCT38074 is a 3.3V clock driver built using advanced CMOS
technology. Thislowskewclockdriveroffers1:4fanout. Thelargefanoutfrom
a single input reduces loading on the preceding driver and provides an efficient
clock distribution network. Multiple power and grounds reduce noise. Typical
applications are clock and signal distribution.
