IDT74FCT38074 3.3V CMOS 1-TO-4 CLOCK DRIVER INDUSTRIAL TEMPERATURE RANGE 3.3V CMOS IDT74FCT38074 1-TO-4 CLOCK DRIVER DESCRIPTION: FEATURES: The FCT38074 is a 3.3V clock driver built using advanced CMOS Advanced CMOS Technology technology. This low skew clock driver offers 1:4 fanout. The large fanout from Guaranteed low skew < 100ps (max.) a single input reduces loading on the preceding driver and provides an efficient Very low duty cycle distortion< 250ps (max.) clock distribution network. Multiple power and grounds reduce noise. Typical High speed propagation delay< 3ns (max.) applications are clock and signal distribution. 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 FUNCTIONAL BLOCK DIAGRAM PIN CONFIGURATION O1 8 VCC 1 O4 7 VCC 2 O3 O2 IN 6 O2 3 IN 5 GND 4 O1 O3 O4 SOIC TOP VIEW The IDT logo is a registered trademark of Integrated Device Technology, Inc.
