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. Features: Two Independent Comparators Operates from a Single 5V Supply Typically 80ns Response Time at 15V Minimum FanOut of 2 Each Side Maximum Input Current of 1 A Over Temperature Inputs and Outputs can be Isolated from System Ground High Common Mode Slew Rate Absolute Maximum Ratings: Total Supply Voltage . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 36V Output to Negative Supply Voltage . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 36V Ground to Negative Supply Voltage . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 25V Ground to Positive Supply Voltage . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 18V Differential Input Voltage . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5V Input Voltage (Note 1) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 15V Power Dissipation (Note 2) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 500mW Output Short Circuit Duration . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10sec Operating Temperature Range . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0 to +70C Storage Temperature Range . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 65 to +150C Lead Temperature (Soldering 10 sec) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . +260C Note 1. For supply voltages less than 15 the absolute maximum input voltage is equal to the supply voltage. Note 2. The maximum junction temperature is 85C. For operating at elevated temperatures, de- vices must be derated based on a thermal resistance of 100C/W, junction to ambient.Electrical Characteristics: (Note 3) Parameter Test Conditions Min Typ Max Unit Input Offset Voltage T = +25C, R 5k, Note 4 2.0 8.0 mV A S Input Offset Current T = +25C, Note 4 80 200 nA A Input Bias Current T = +25C 250 1000 nA A Voltage Gain T = +25C, Note 6 8 40 V/mV A Response Time T = +25C, V = 15V, Note 5 80 ns A S Saturation Voltage V 10mV, I = 25mA T = +25C 0.75 1.5 V IN OUT A Output Leakage Current V 10mV, V = 35V, V = V = 0V, 0.2 10 A IN OUT GND T = +25C A Input Offset Voltage R 5k, Note 4 10 mV S Input Offset Current Note 4 300 nA Input Bias Curent 1200 nA Input Voltage Range V = 15V 13 V S V+ = 5V, V = 0 1 3 V Saturation Voltage V+ 4.5V, V = 0, V 10mV, I 3.2mA 0.3 0.4 V IN SINK Differential Input Voltage 5 V Positive Supply Current T = +25C, V+ = 5V, V = 0 4.3 mA A Positive Supply Current T = +25C, V = 15V 8 12.5 mA A S Negative Supply Current T = +25C, V = 15V 3 5 mA A S Note 3.

S A 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 V . S 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 1.4 resistor. Pin Connection Diagram N.C. 1 14 N.C. N.C. 2 13 N.C.
