IDT74FCT3807/A 3.3V CMOS 1-TO-10 CLOCK DRIVER COMMERCIAL/INDUSTRIAL TEMPERATURE RANGES 3.3V CMOS 1-TO-10 CLOCK DRIVER DESCRIPTION: FEATURES: * * * * * * * * * * * * * IDT74FCT3807/A The FCT3807/A 3.3V clock driver is built using advanced dual metal CMOS technology. This low skew clock driver offers 1:10 fanout. The large fanout from a single input reduces loading on the preceding driver and provides an efficient clock distribution network. The FCT3807/A offers low capacitance inputs with hysteresis for improved noise margins. Multiple power and grounds reduce noise. Typical applications are clock and signal distribution. 0.5 MICRON CMOS Technology Guaranteed low skew < 350ps (max.) Very low duty cycle distortion < 350ps (max.) High speed: propagation delay < 3ns (max.) Very low CMOS power levels TTL compatible inputs and outputs 1:10 fanout Maximum output rise and fall time < 1.5ns (max.) Maximum operating frequency of 133.33MHz Low input capacitance: 4.5pF typical VCC = 3.3V 0.3V Inputs can be driven from 3.3V or 5V components Available in SSOP, SOIC, and QSOP packages PIN CONFIGURATION FUNCTIONAL BLOCK DIAGRAM O1 O2 O3 O4 O5 IN O6 IN 1 20 VCC GND 2 19 O10 O1 3 18 O9 VCC 4 17 GND O2 5 16 O8 GND 6 15 VCC O3 7 14 O7 VCC 8 13 GND O4 9 12 O6 10 11 O5 GND O7 SOIC/ SSOP/ QSOP TOP VIEW O8 O9 O 10 The IDT logo is a registered trademark of Integrated Device Technology, Inc.
