SGM8704
Micro-Power, CMOS Input, RRIO, 1.4V,
Push-Pull Output Comparator
GENERAL DESCRIPTION
FEATURES
The SGM8704 is an ultra low power comparator with a
typical power supply current of 300nA. It has the
best-in-class power supply current versus propagation
delay performance. The propagation delay is as low as
6μs with 100mV overdrive at 1.4V supply.
Designed to operate over a wide range of supply voltages,
from 1.4V to 5.5V, with guaranteed operation at 1.4V,
2.5V and 5.0V, the SGM8704 is ideal for use in a variety
of battery-powered applications. With rail-to-rail common
mode voltage range, the SGM8704 is well suited for
single-supply operation. The SGM8704 features
complementary outputs and has a latch enable input
(LE ). Its small packages make this device ideal for use in
handheld electronics and mobile phone applications.
Featuring a push-pull output stage, the SGM8704 allows
for operation with absolute minimum power consumption
when driving any capacitive or resistive load.
Ultra Low Power Consumption:
300nA (TYP) at VS = 1.4V
Wide Supply Voltage Range: 1.4V to 5.5V
Propagation Delay: 6μs (TYP) at VS = 1.4V
Push-Pull Output Current Drive:
19mA (TYP) at VS = 5V
Rail-to-Rail Input
Latch Function Included
-40to +85Operating Temperature Range
Available in Green SOIC-8 and MSOP-8 Packages
APPLICATIONS
RC Timers
Window Detectors
IR Receiver
Multivibrators
Alarm and Monitoring Circuits
SGM8704 is available in Green SOIC-8 and MSOP-8
packages. It is rated over the -40°C to +85°C
temperature range.

NOTE:
Stresses beyond those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device. These
are stress ratings only, and functional operation of the device at
these or any other conditions beyond those indicated in the
operational sections of the specifications is not implied.
Exposure to absolute maximum rating conditions for extended
periods may affect device reliability.

CAUTION
This integrated circuit can be damaged by ESD if you don’t pay
attention to ESD protection. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failure to observe proper handling and installation procedures
can cause damage. ESD damage can range from subtle
performance degradation to complete device failure. Precision
integrated circuits may be more susceptible to damage because
very small parametric changes could cause the device not to
meet its published specifications.
SGMICRO reserves the right to make any change in circuit
design, specification or other related things if necessary without
notice at any time. Please contact SGMICRO sales office to get
the latest datasheet.
