IDT74FCT20807 2.5V CMOS 1-TO-10 CLOCK DRIVER INDUSTRIAL TEMPERATURE RANGE 2.5V CMOS 1-TO-10 CLOCK DRIVER IDT74FCT20807 FEATURES: • • • • • • • • • • • DESCRIPTION: High frequency > 150MHz Guaranteed low skew < 150ps (max.) between any two outputs Very low duty cycle distortion < 300ps High speed: propagation delay < 3ns Very low CMOS power levels 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 The FCT20807 is a 2.5V compatible, high speed, low noise, 1:10 fanout, non-inverting clock buffer. The large fanout from a single input reduces loading on the preceding driver and provides an efficient clock distribution network. Providing output to output skew as low as 150ps, the FCT20807 is an ideal clock distribution device for synchronous systems. Multiple power and grounds reduce noise. Typical applications are clock and signal distribution.
