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 NC STROBE A
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 INPUT B OUTPUT A
applications for analog voltage comparators.

Frequently Asked Questions
What is the difference between the NE527 and the NE529?
The NE527 incorporates an “Emitter-Follower” input stage compared to the NE529, providing extremely low input currents.
Can this comparator handle unbalanced supply voltages?
Yes, Output A does not need V+ and V- to be balanced. However, negative supply (V-) must always be at least 1.6V more than ground.
What is the maximum allowable power dissipation for the NE527?
The N package has a max power dissipation of 1420 mW at 25°C, while the D package is limited to 1040 mW.
Does the NE527 support various interface types?
Yes, applications include ECL-to-TTL interface, TTL-to-ECL interface, and general A/D conversion.
What are the available packaging options for the NE527?
It is available in a 14-Pin Plastic Dual In-Line Package (DIP) or a 14-Pin Small Outline (SO) package.
