FAN256 — Dual Low Voltage Comparator
Features
Description
The FAN256 is a low -pow er, dual comparator that
typically consumes less than 10µA supply current per
comparator. Guaranteed to operate at a low voltage of
1.6V and fully operational up to 5.5V, it is convenient for
use in 1.8, 3.0V, and 5.0V systems.
.
.
.
Low Supply Current: IDD=7μA (Typical)
Single Pow er Supply Operation
Wide Common-Mode Input Voltage Range:
Rail-to-Rail
The FAN256 has a complementary push-pull P- and N-
channel output stage capabile of driving a rail-to-rail
output sw ing w ith a load ranging up to 5.0mA .

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.
