NTE919D Integrated Circuit High Speed Dual Comparator Description: The NTE919D is a precision high speed dual comparator fabricated on a single monolithic chip. This devices is designed to operate over a wide range of supply voltages down to a single 5V logic supply and ground. Further, it has higher gain and lower input currents than devices like the NTE910. The uncommitted collector of the output stage makes it compatible with RTL, DTL, and TTL as well as capable of driving lamps and relays at currents up to 25mA. Although designed primarily for applications requiring operation from digital logic supplies, the NTE919D is fully specified for power supplies up to ±15V.

For supply voltages less than ±15 the absolute maximum input voltage is equal to the supply voltage. Note 2. The maximum junction temperature is 85°C. For operating at elevated temperatures, devices must be derated based on a thermal resistance of 100°C/W, junction to ambient.

These specifications apply for VS = ±15V, and 0°C ≤ TA ≤ 70°C, unless otherwise stated. The offset voltage, offset current and bias current specifications apply for any supply voltage from a single 5V supply up to ±15V supplies. Do not operate the device with more than 16V from ground to VS. Note 4. 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 5. The response time specified is for a 100mV input step with 5mV overdrive. Note 6. Output is pulled up to 15V through a 1.4Ω resistor. Pin Connection Diagram N.C. 1 14 N.C. N.C. 2 13 N.C.
