LMx19 High Speed Dual Comparator 1 Features 2 Description
• Two Independent Comparators The LM119 series are precision high-speed dual 1 comparators fabricated on a single monolithic chip. • Operates from a Single 5-V Supply They are designed to operate over a wide range of • Typically 80-ns Response Time at ±15 V supply voltages down to a single 5-V logic supply and • Minimum Fan-out of 2 Each Side ground. They have higher gain and lower input currents than devices such as the LM710. The • Maximum Input Current of 1 μA Over uncommitted collector of the output stage makes the Temperature LM119 compatible with RTL, DTL, and TTL, as well • Inputs and Outputs can be Isolated from System as capable of driving lamps and relays at currents of Ground up to 25 mA. • High Common-Mode Slew Rate The LM319A offers improved precision over the standard LM319, with tighter tolerances on offset

voltage, offset current, and voltage gain. Although designed primarily for applications requiring operation from digital logic supplies, the LM119 series are fully specified for power supplies up to ±15 V. The series features faster response than the LM111, at the expense of higher power dissipation. However, the high-speed, wide operating voltage range and low package count make the LM119 more versatile than older devices such as the LM711. The LM119 is specified from −55°C to +125°C, the LM219 is specified from −25°C to +85°C, and the LM319A and LM319 are specified from 0°C to +70°C.
