General Description
The TS393 is dual independent precision voltage comparators capable of single-supply or split-supply operation. The
specifications as low as 2.0 mV make this device an excellent ground level with single-supply operation. Input
offset-voltage selection for many applications in consumer automotive, and It is designed to permit a common mode
range-to- industrial electronics.
The TS393 is offered in 8 pin SOP-8 and DIP-8 package.

CC
Note 2. This magnitude of input current will only occur if the input leads are driven more negative than ground or the
negative supply voltage. This is due to the input PNP collector base junction becoming forward biased acting as
an input clamp diode. There is also a lateral PNP parasitic transistor action on the IC chip. This phenomena can
cause the output voltage of the comparators to go to the V
voltage level (or ground if overdrive is large) during
CC
the time the input is driven negative. This will not destroy the device and normal output states will recover when
the inputs become -0.3V of ground or negative supply.

Note 4. Due to the PNP transistor inputs, bias current will flow out of the inputs, this current is essentially constant
independent of the output state, therefore, no loading changes will exist on the input lines.
Note 5. Input common mode of either input should not be permitted to go more than 0.3V negative of ground or minus
supply. The upper limit of common mode range is V
- 1.5V but either or both inputs can betaken to as high as

30volts without damage.
Note 6. Response time is specified with a 100mV step and 5.0mV of overdrive. With larger magnitudes of overdrive
faster response times are obtainable.
Note 7. The comparator will inhibit proper output state if one of the inputs is become greater than V

Applications Information
This dual comparator feature high gain, wide bandwidth characteristics. This gives the device oscillation tendencies if
the outputs are capacitive coupled to the inputs via stray capacitance. This oscillation manifests itself during output
transitions (V
feedback (<10 mV) is also recommended.
It is good design practice to ground all unused pins. Differential input voltages may be larger than supply voltage
without damaging the comparator's inputs. Voltages more negative than -0.3V should not be used.
