Quad voltage comparator
LM139/239/239A/339/339A
/LM2901/MC3302
DESCRIPTION
The LM139 series consists of four independent precision voltage
comparators, with an offset voltage specification as low as 2.0mV
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.

D Package at 8.3mW/°C
2. Short circuits from the output to V+ can cause excessive heating and eventual destruction. The maximum output current is approximately
20mA 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 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 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 –0.3V
