The LM239 and LM139 must be derated based on a 150˚C maximum junction temperature. The low bias dissipation and the “ON-OFF” characteristic of the outputs keeps the chip dissipation ver y small (PD≤100 mW), provided the output transistors are allowed to saturate. Note 2: Short circuits from the output to V+ can cause excessive heating and eventual destruction. When considering short circuits to ground, the maximum output current is approximately 20 mA independent of the magnitude of V +. Note 3: This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of the input PNP transistors becoming forward biased and thereby acting as input diode clamps. In addition to this diode action, there is also lateral NPN parasitic tr ansistor action on the IC chip. This transistor action can cause the output voltages of the comparators to go to the V + voltage level (or to ground for a large overdrive) for the time duration that an input is driven negative. This is not destructive and normal output states will re-establish when the input voltage, which was negative, again returns to a value greater than −0.3 V DC (at 25˚)C. Note 4: These specifications are limited to −55˚C ≤ TA ≤ +125˚C, for the LM139/LM139A. With the LM239/LM239A, all temperature specifications are limited to −25˚C ≤ TA ≤ +85˚C, the LM339/LM339A temperature specifications are limited to 0˚C ≤ TA ≤ +70˚C, and the LM2901, LM3302 temperature range is −40˚C ≤ TA ≤ +85˚C. Note 5: The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of the outpu ts o no loading change exists on the reference or input lines. Note 6: The input common-mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of the common-mode voltage range is V + −1.5V at 25˚C, but either or both inputs can go to +30 V DC without damage (25V for LM3302), independent of the magnitude of V +. Note 7: The response time specified is a 100 mV input step with 5 mV overdrive. For larger overdrive signals 300 ns can be obtained, see typical performance characteristics section. Note 8: Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the common-mode range, the comparator will provide a proper output state. The low input voltage state must not be less than −0.3 V DC (or 0.3 VDCbelow the magnitude of the negative power supply, if used) (at 25˚C). Note 9: At output switch point, VO.1.4 VDC,R S =0 Ω with V+ from 5 VDC to 30 VDC; and over the full input common-mode range (0 VDC to V+ −1.5 VDC), at 25˚C. For LM3302, V+ from 5 VDC to 28 VDC.

The LM139 series are high gain, wide bandwidth devices which, like most comparators, can easily oscillate if the output lead is inadvertently allowed to capacitively couple to the inputs via stray capacitance. This shows up only during the output voltage transition intervals as the comparator changes states. Power supply bypassing is not required to solve this problem. Standard PC board layout is helpful as it reduces stray input-output coupling. Reducing this input re- sistors to < 10 kΩ reduces the feedback signal levels and finally, adding even a small amount (1 to 10 mV) of positive feedback (hysteresis) causes such a rapid transition that oscillations due to stray feedback are not possible. Simply socketing the IC and attaching resistors to the pins will cause input-output oscillations during the small transition intervals unless hysteresis is used. If the input signal is a pulse waveform, with relatively fast rise and fall times, hysteresis is not required. All pins of any unused comparators should be tied to the negative supply. The bias network of the LM139 series establishes a drain current which is independent of the magnitude of the power supply voltage over the range of from 2 V DC to 30 VDC. It is usually unnecessary to use a bypass capacitor across the power supply line. The differential input voltage may be larger than V + without damaging the device. Protection should be provided to pre- vent the input voltages from going negative more than −0.3 V DC (at 25˚C). An input clamp diode can be used as shown in the applications section. The output of the LM139 series is the uncommitted collector of a grounded-emitter NPN output transistor. Many collectors can be tied together to provide an output OR’ing function. An output pull-up resistor can be connected to any available power supply voltage within the permitted supply voltage range and there is no restriction on this voltage due to the magnitude of the voltage which is applied to the V + terminal of the LM139A package. The output can also be used as a simple SPST switch to ground (when a pull-up resistor is not used). The amount of current which the output device can sink is limited by the drive available (which is independent of V +) and the β of this device. When the maximum current limit is reached (approximately 16 mA), the output transistor will come out of saturation and the output voltage will rise very rapidly. The output saturation voltage is limited by the ap- proximately 60Ω R SAT of the output transistor. The low offset voltage of the output transistor (1 mV) allows the output to clamp essentially to ground level for small load currents.
