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.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. 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.
