DESCRIPTION
The NE527 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. The NE527 is similar in design to the
Philips Semiconductors NE529 voltage comparator except that it
incorporates an “Emitter-Follower” input stage for extremely low
input currents. This opens the door to a whole new range of
applications for analog voltage comparators.
FEATURES
•15ns propagation delay
•Complementary output gates
•TTL or ECL compatible outputs
•Wide common-mode and differential voltage range
•Typical gain of 5000
