DESCRIPTION
The LM139 series consists of four independent precision voltage comparators, with an offset voltage specification as low as 2.0 mV max for each comparator, which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. These comparators also have a unique characteristic in that the input common-mode voltage range includes ground, even though they are operated from a single power supply voltage. The LM139 series was designed to directly interface with TTL and CMOS. When operated from both plus and minus power supplies, the LM139 series will directly interface with MOS logic where their low power drain is a distinct advantage over standard comparators.

NOTES: 1. Derate above 25 °C, at the following rates: N Package at 11.4 mW/°C D Package at 8.3 mW/°C DH Package at 6.1 mW/°C 2. Short circuits from the output to V+ can cause excessive heating and eventual destruction. The maximum output current is approximately 20 mA independent of the magnitude of V+. 3. This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collectorbase 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 transistor 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 reestablish when the input voltage, which was negative, again returns to a value greater than 0.3 VDC.
