IDT74FCT38075 3.3V CMOS 1-TO-5 CLOCK DRIVER INDUSTRIAL TEMPERATURE RANGE 3.3V CMOS 1-TO-5 CLOCK DRIVER IDT74FCT38075 FEATURES: DESCRIPTION: • • • • • • • • • • • • • The FCT38075 is a 3.3V clock driver built using advanced CMOS technology. This low skew clock driver offers 1:5 fanout. The large fanout from 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. 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 1:5 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 PIN CONFIGURATION FUNCTIONAL BLOCK DIAGRAM O1 O2 IN O3 O4 O5 1 8 O4 VCC 2 7 O3 IN 3 6 O2 GND 4 5 O1 SOIC TOP VIEW O5 The IDT logo is a registered trademark of Integrated Device Technology, Inc.
