LM393W with internal ESD protection: 2 kV HBM
Description
The LM193, LM293, LM393 and LM393W 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.
The LM393W offers additional ESD robustness of 2 kV HBM on all pins.

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.

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.
