IDT74FCT20807 2.5V CMOS 1-TO-10 CLOCK DRIVER INDUSTRIAL TEMPERATURE RANGE 2.5V CMOS IDT74FCT20807 1-TO-10 CLOCK DRIVER DESCRIPTION: FEATURES: The FCT20807 is a 2.5V compatible, high speed, low noise, 1:10 fanout, High frequency > 150MHz non-inverting clock buffer. The large fanout from a single input reduces loading Guaranteed low skew < 150ps (max.) between any two outputs on the preceding driver and provides an efficient clock distribution network. Very low duty cycle distortion < 300ps Providing output to output skew as low as 150ps, the FCT20807 is an ideal clock High speed: propagation delay < 3ns distribution device for synchronous systems. Multiple power and grounds Very low CMOS power levels reduce noise. Typical applications are clock and signal distribution. TTL compatible inputs and outputs 1:10 fanout Maximum output rise and fall time < 1.25ns (max.) Low input capacitance: 3pF typical 2.5V supply voltage Available in SSOP and QSOP packages PIN CONFIGURATION FUNCTIONAL BLOCK DIAGRAM O1 IN 1 20 VCC GND 2 O10 19 O2 1 O 3 18 O9 17 VCC 4 GND O3 O2 O8 5 16 O4 GND 6 15 VCC O3 O7 7 14 O5 VCC 8 13 GND IN O4 O6 12 9 O6 GND 11 O5 10 O7 SSOP/ QSOP TOP VIEW O8 O9 O10 The IDT logo is a registered trademark of Integrated Device Technology, Inc.
