Available in 20pin 300mil wide SOIC package DESCRIPTION: Potato Semiconductor's PO49HSTL32807G is designed for world top performance using submicron CMOS technology to achieve 400MHz TTL output frequency with less than 200ps output pulse skew. PO49HSTL32807G is a 1.65v to 3.6V 1 high speed comparator inputs to 10 TTL output buffered driver to achieve higher than 400MHz output frequency with integrated series damping resistors on all outputs to match 50 ohm transmission line impedance. Typical applications are HSTL, PECL, LVDS to TTL translator, crystal or ring oscillator, clock and signal distribution.
