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.
FEATURES
10ns propagation delay
Complementary output gates
TTL or ECL compatible outputs
Wide common-mode and differential voltage range
Typical gain 5000

APPLICATIONS
One of the main features of the device is that supply voltages (V+,
V-) need not be balanced, as in the following diagrams. For proper
operation, however, negative supply (V-) should always be at least
6V more than the ground terminal (pin 6). Input Common-Mode
range should be limited to values of 2V less than the supply voltages
(V+ and V-) 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.
