Description
The TS391H is a low power voltage comparator designed specifically to operate from a single supply over a wide range of voltages. Operation from split power supplies is also possible.
This comparator also has a unique characteristic in that the input common-mode voltage range includes ground even though operated from a single power supply voltage.

1.
Short-circuits from the output to V
CC

can cause excessive heating and potential destruction. The maximum output current is approximately 20 mA independent of the magnitude of V

.
2.
Short-circuits can cause excessive heating. These values are typical.
3.
Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a
1.5 k
Ω resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating.
4.
Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5
Ω
). This is done for all couples of connected pin combinations while the other pins are floating.
5.
Charged device model: all pins and package are charged together to the specified voltage and then discharged directly to ground through only one pin. This is done for all pins.

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.
