FAN156 Low Voltage Comparator Features Description The FAN156 is a low-power single comparator that typically consumes less than 10µA of supply current. It is guaranteed to operate at a low voltage of 1.6V and is fully operational up to 5.5V, making it convenient for use in 1.8, 3.0V, and 5.0V systems. Low Supply Current: IDD 6μA (Typical) Single Power Supply Operation Wide Common-Mode Input Voltage Range Push-Pull Output Circuit The FAN156 has a complementary push-pull P- and Nchannel output stage capable of driving a rail-to-rail output swing with a load ranging up to 5.0mA.

The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only.
