Potato Semiconductor’s PO49FCT32803G is
designed for world top performance using
submicron
CMOS
technology
to
achieve
500MHz output frequency with less than 250ps
output skew.
PO49FCT32803G is a 3.3V CMOS 1 input to 7
Output Buffered Driver with integrated series
damping resistors on all outputs to match 50 ohm
transmission line impedance. Typical applications
are clock and signal distribution.
