IDT74FCT38074 3.3V CMOS 1-TO-4 CLOCK DRIVER INDUSTRIAL TEMPERATURE RANGE 3.3V CMOS 1-TO-4 CLOCK DRIVER IDT74FCT38074 FEATURES: DESCRIPTION: FUNCTIONAL BLOCK DIAGRAM PIN CONFIGURATION • • • • • • • • • • • • • The FCT38074 is a 3.3V clock driver built using advanced CMOS technology. This low skew clock driver offers 1:4 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 1:4 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 O1 VCC 1 8 O4 VCC 2 7 O3 IN 3 6 O2 GND 4 5 O1 O2 IN O3 SOIC TOP VIEW O4 The IDT logo is a registered trademark of Integrated Device Technology, Inc.
