PI49FCT807T Fast CMOS Clock Driver Features Description Guaranteed low skew: 0.25ns Pericom Semiconductors PI49FCT807T clock driver feature one Low input capacitance 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 Minimum duty cycle distortion part. Typical applications are clock and signal distribution. 1:10 fanout High speed: 3.5ns propagation delay TTL input and CMOS output compatible V = 3.3V (typ.) OH V = 0.3V (typ.)
