BIPOLAR ANALOG INTEGRATED CIRCUIT
µ
PC339
LOW POWER QUAD COMPARATOR
DESCRIPTION
The µPC339 is a quad comparator which is designed
to operate from a single power supply over a wide range
of voltage. Operation from split power supplies, is also
possible and the power supply current drain is very low.
Further advantage, the input common-mode voltage includes ground, even though operated from a single power
FEATURES
• Common-mode input voltage range includes V
• Wide supply voltage range
2 V to 32 V (Single)
±1 V to ±16 V (Split)
• Low supply current
• Open collector output
supply voltage.

Notes 1. Reverse connection of supply voltage can cause destruction.
2. The input voltage should be allowed to input without damage or destruction independent of the
magnitude of V+. Either input signal should not be allowed to go negative by more than 0.3 V. The normal
operation will establish when any input is within the Common Mode Input Voltage Range of electrical
characteristics.
3. This specification is the voltage which should be allowed to supply to the output terminal from external
without damage or destruction independent of the magnitude of V
of supply voltage, power on/off etc., this specification should be kept.
4. Thermal derating factor is –7.6 mW/°C when operating ambient temperature is higher than 55 °C.
5. Thermal derating factor is –5.5 mW/°C when operating ambient temperature is higher than 25 °C.
6. Short circuits from the output to V
dissipation not to exceed the absolute maximum ratings, Note 4 and Note 5.
