NE527
DESCRIPTION
PIN CONFIGURATIONS
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.

range should be limited to values of 2V less than the supply voltages
(V1+ and V1-) up to a maximum of ±5V as supply voltages are
increased. It is also important to note that Output A is in phase with
Input A and Output B is in phase with Input B.
APPLICATIONS
One of the main features of the device is that supply voltages (V1+,
V1-) need not be balanced, as in the following diagrams. For proper
operation, however, negative supply (V1-) should always be at least
6V more than the ground terminal (Pin 6). Input common-mode
