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 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. Operation beyond the limits of this table may impair the useful life of the device.
2. The LM139/139A must be derated on a 150°C max. junction temperature. The low power dissipation and the “On-Off” characteristics of the
outputs keep the chip dissipation very small (PD <100mW), provided the output transistors are allowed to saturate.
3. Short circuits from the output to V+ can cause excessive heating and eventual destruction. The max. output current is approximately 20mA
independent of the magnitude of V+.
4. 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 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 re-establish when the input voltage, which was negative, again returns to a value greater than -0.3VDC.
5. Positive excursions of input voltage may exceed the power supply level by 17V. 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 -0.3VDC (or
0.3VDC below the magnitude of the negative power supply, if used).
6. At output switch point, VO 1.4VDC, RS = 100with V+ from 5VDC to 30VDC, & over the full input common-mode range (0VDC to V+
-1.5VDC).
7. 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, but either or both inputs can go to 30VDC without damage.
8. 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 output so no loading change exists on the reference or input lines.
9. The response time specified is for a 100mV input step with a 5mV overdrive. For larger overdrive signals, 300ns can be obtained. See
Typical Performance Characteristics section.
10. Operation beyond the limits of this table may impair the useful life of the device.
