DESCRIPTION:
Potato Semiconductor’s PO100HSTL180A is
designed for world top performance using
submicron CMOS technology to achieve 1GHz
LVTTL output frequency with less than 1.8ns
propagation delay and 1.65GHz HSTL output
frequency with less than 1.4ns propagation delay.
The
PO100HSTL180A
is a low-skew, The small
outline 14 pin package and the low skew design to
make it ideal for applications which require the
translation of a clock or a data signal.
