The open collector of the output stage makes them compatible with transistor-transistor logic (TTL) as well as capable of driving lamps and relays at currents up to 25 mA. Although designed primarily for applications requiring operation from digital logic supplies, these comparators are fully specified for power supplies up to ±15 V. They feature faster response times than the LM111 at the expense of higher current consumption. However, the high speed, wide operating voltage range and low package count make the LM119, LM219, and LM319 much more versatile.

For supply voltages lower than ±15 V the absolute maximum input voltage is equal to the supply voltage. 2. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous shortcircuits on all amplifiers. 3. Rth are typical values. 4. Human body model: 100 pF discharged through a 1.5 kΩ resistor between two pins of the device, done for all couples of pin combinations with other pins floating. 5. Machine model: a 200 pF cap is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5 Ω), done for all couples of pin combinations with other pins floating. 6. Charged device model: all pins and the package are charged together to the specified voltage and then discharged directly to the ground through only one pin. This is done for all pins. Table 2.

These specifications apply for VCC = ±15 V, unless otherwise stated.The offset voltage, offset current and bias current specifications apply for any supply voltage from a single +5 V up to ±15 V supplies. The offset voltages and offset current given are the maximum values required to drive the output down to 1V or up to +14 V with a 1 mA load current. Thus, these parameters define an error band and take into account the worst case effects of voltage gain and input impedance. 2. At output switch point, Vo ≈ 1.4 V, no load, with VCC from 5 V to ±15 V and over the full input common-mode range. 3. The response time specified is for a 100 mV input step with 5 mV overdrive.
