NE529
DESCRIPTION
The NE529 is a high-speed analog voltage comparator which, for
the first time, mates state-of-the-art Schottky diode technology with
the conventional linear process. This allows simultaneous
fabrication of high-speed TTL gates with a precision linear amplifier
on a single monolithic chip.
