NE527 is a product manual from Philips Semiconductors. It is a high-precision analog voltage comparator with 15ns propagation delay, complementary output gates, TTL or ECL compatible outputs, wide common-mode and differential voltage range, and 5000 typical gain.
The NE527 is a high‑speed analog voltage comparator that combines Schottky diode technology with a conventional linear process, enabling fast TTL gates and a precision linear amplifier on a single chip. It features a complementary output stage, TTL or ECL compatible outputs, and a wide common‑mode voltage range.
Typical applications include A/D conversion, ECL‑to‑TTL and TTL‑to‑ECL interfacing, memory sensing, and optical data coupling. The device operates from asymmetric supply voltages and offers low input currents for sensitive analog circuits.
