NTE919 Integrated Circuit High Speed Dual Comparator Description: The NTE919 is a precision high speed dual comparator designed to operate over a wide range of supply voltages down to a single 5V logic supply and ground and have low input currents and high gains. The open collector of the output stage makes it compatible with TTL as well as capable of driving lamps and relays at currents up to 25mA. Although designed primarily for for applications requiring operation from digital logic supplies, are fully specified for power supplies up to ±15V.

The offset voltages and offset currents given are the maximum values required to drive the output within a volt of either supply with a 1mA load. Thus, these parameters define an error band and take into account the worst case effects of voltage gain and input impedance. Note 3. The response time specified is for a 100mV input step with 5mV overdrive.
