FN6152.3
Ultra-Small, 800nA and 2.5µA Single
Supply, Rail-to-Rail Input/Output (RRIO)
www.Cdaotamshepeta4ur.acotomrs
The ISL28196 and ISL28197 are micropower comparators
optimized for low-power applications. The parts are
designed for single-supply operation from 1.8V to 5.5V. The
ISL28197 typically consumes 800nA of supply current and
the ISL28196 typically consumes 2.5µA of supply current.
Both parts feature rail-to-rail input and output swing (RRIO),
allowing for maximum battery usage. The ISL28196 features
a propagation delay of 150µs and the ISL28197 features a
propagation delay of 0.6ms.
Equipped with an ENABLE pin (EN), both parts draw
typically 2nA when off. The combination of small footprint,
low power, single supply, and rail-to-rail operation makes
them ideally suited for all battery operated devices.

NOTES:
1. These Intersil Pb-free plastic packaged products employ special Pb-
free material sets; molding compounds/die attach materials and
100% matte tin plate PLUS ANNEAL - e3 termination finish, which is
RoHS compliant and compatible with both SnPb and Pb-free
soldering operations. Intersil Pb-free products are MSL classified at
Pb-free peak reflow temperatures that meet or exceed the Pb-free
requirements of IPC/JEDEC J STD-020.
2. These Intersil Pb-free plastic packaged products employ special Pb-
free material sets; molding compounds/die attach materials and
NiPdAu plate - e4 termination finish, which is RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.
3. Please refer to TB347 for details on reel specifications.
1 CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.

CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and
result in failures not covered by warranty.
NOTE:
4. θJA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typ values are for information purposes only. Unless otherwise noted, all tests are at
the specified temperature and are pulsed tests, Therefore TJ = TC = TA
Electrical Specifications V+ = 5V, V- = 0V, VCM = 2.5V, TA = +25°C, unless otherwise specified. Boldface limits apply over -40°C to
+125°C.
