Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please
email any questions regarding the system integration to Fairchild_questions@onsemi.com.

FAN156
Low Voltage Comparator
Features
Description
The FAN156 is a low-power single comparator that
typically consumes less than 10 µA of supply current. It
is guaranteed to operate at a low voltage of 1.6 V and is
fully operational up to 5.5 V, making it convenient for
use in 1.8, 3.0 V, and 5.0 V systems.
Low Supply Current: IDD 6 μA (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 5.0 mA.

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.
