NTE943 Description

Short technical summary and product information.

The NTE943, NTE943M, and NTE943SM are integrated circuits featuring two independent precision voltage comparators. They are designed to operate from a single power supply ranging from 2.0V to 36V, or from split supplies of ±1.0V to ±18V. The low power supply current drain is independent of the supply voltage magnitude.

Key electrical characteristics include a low input biasing current of 25nA, a low input offset current of ±5nA, and a maximum offset voltage of ±3mV. The input common-mode voltage range includes ground, even when operated from a single supply. The output voltage is compatible with TTL, DTL, ECL, MOS, and CMOS logic systems, with a low output saturation voltage of 240mV at 4mA.

These comparators are available in three different case styles: 8-Lead Metal Can (NTE943), 8-Lead Mini DIP (NTE943M), and 8-Lead SOIC (Surface Mount) (NTE943SM). Applications include limit comparators, analog-to-digital converters, pulse and time delay generators, and logic gates.
