PI49FCT807TQE

PI49FCT807T Fast CMOS Clock Driver Features Description       Pericom Semiconductor’s PI49FCT807T clock driver feature one input and ten outputs. The large fanout from a single input line reduces loading on input clock. TTL level outputs reduce noise levels on the part. Typical applications are clock and signal distribution. Guaranteed low skew: 0.25ns Low input capacitance Minimum duty cycle distortion 1:10 fanout High speed: 3.5ns propagation delay TTL input and CMOS output compatible – VOH = 3.3V (typ.) – VOL = 0.3V (typ.)  Industrial Operation at -40ºC to +85ºC  Packaging (Pb-free & Green available): – 20-pin 150-mil wide QSOP (Q) – 20-pin 300-mil SOIC (S) Pin Configuration A GND B0 VCC B1 GND B2 VCC B3 GND Block Diagram 1 2 20 19 VCC 3 4 5 6 7 8 9 10 18 17 16 15 14 13 12 11 B8 B0 B9 B1 GND B2 B7 VCC B3 B6 B4 GND A B5 B5 B4 B6 Pin Description Pin Name A B0 - B9 GND VCC 09-0006 B7 Description Input Outputs Ground Power B8 B9 1 PS7008G 11/25/09 PI49FCT807T Fast CMOS Clock Driver Maximum Ratings (Above which the useful life may be impaired.
