DESCRIPTION
These devices consist of four independent preci-
sion voltage comparators with an offset voltage
specifications as low as 2mV max for LM339A,
LM239A and LM139A. All these comparators
were designed specifically to operate from a sin-
gle power supply aver a wide range of voltages.
Operation from split power supplies is also possi-
ble.

These comparators also have a unique character-
istic in that the input common-mode voltage range
includes ground even though operated from a sin-
gle power supply voltage.

Short-circuits from the output to VCC +can cause excessive heating and eventual destruction. The maximum output current is approximately 20mA
independent of the magnitude of VCC

2.
At output switch point, Vo ≈ 1.4V, Rs = 0 with VCC+ from 5V to 30V, and over the full common-mode range (0V to VCC+ -1.5V).
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 charge exists on the reference of input lines.
3.
The input common-mode voltage of 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 VCC+ -1.5V, but either or both inputs can go to +30V without damage
4.
5.
The response time specified is for a 100mV input step with 5mV overdrive. For larger overdrive signals 300ns can be obtained
Posistive 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 -0.3V (or 0.3V bellow the negative power supply, if
used).
