PRELIMINARY DATA SHEET
BIPOLAR ANALOG INTEGRATED CIRCUIT
μ PC277GR-9LG, 393GR-9LG
LOW POWER DUAL COMPARATORS
DESCRIPTION
The μ PC277GR-9LG, 393GR-9LG are quad comparators which are 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 supply voltage.
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
