Low input offset current: ±3 nA typ.
Low input offset voltage: ±1 mV typ.
Input common-mode voltage range includes
ground

Description
The LM193, LM293, and LM393 devices consist
of two independent low voltage comparators
designed specifically to operate from a single
supply over a wide range of voltages. Operation
from split power supplies is also possible.
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.

Notes:
(1)Short-circuits from the output to VCC+ can cause excessive heating and potential destruction. The maximum output current is
approximately 20 mA independent of the magnitude of VCC+.
(2)Short-circuits can cause excessive heating and destructive dissipation. Values are typical.
(3)ESD class definition from AEC-Q100:
(4)HBM class H1B: ESD voltage level from 500 V to 1000 V
(5)MM class M2: ESD voltage level from 100 V to 200 V
(6)CDM class C5: ESD voltage level greater than 1500 V.

high end of the common-mode voltage range is (VCC+) - 1.5 V, but either or both inputs can go to 30 V without damage.

Notes:
(1)At output switch point, Vo = 1.4 V, Rs = 0 with VCC+ from 5 V to 30 V, and over the full common-mode range
(0 V to (VCC+) - 1.5 V).
(2)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)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
(or 0.3 V below the negative power supply, if used).
(4)The response time specified is for a 100 mV input step with 5 mV overdrive. For larger overdrive signals, 300 ns can be
obtained.
