Potato Semiconductor’s PO49FCT32806A is
designed for world top performance using
submicron

CMOS

technology

to

achieve

700MHz TTL output frequency with less than
200ps output pulse skew.
PO49FCT32806A is a 3.3V CMOS Dual 1 input
to 5 outputs Invert Buffered driver to achieve
700MHz output frequency with integrated series
damping resistors on all outputs to match 50 ohm
transmission line impedance. Typical applications
are crystal oscillator, ring oscillator, clock and
signal distribution.
