　　GENERAL DESCRIPTION
　　The ADCMP341/ADCMP343 consist of two low power, high
　　accuracy comparators with a 400 mV reference in an 8-lead
　　SOT-23 package. Operating within a supply range of 1.7 V to
　　5.5 V, the devices only draw 6.5 A (typical), making them ideal
　　for low voltage system monitoring and portable applications.
　　Hysteresis is determined using three resistors in a string configura-
　　tion with the upper and lower tap points connected to the
　　±INA_U and ±INA_L pins of each comparator, respectively.
　　The state of the outputs of the comparators selects which pin is
　　internally connected to the comparators input. Therefore, a
　　change of state in the comparators output results in one of the
　　inputs being switched in to the comparator and the other being
　　switched out. This provides the user with a fully flexible and
　　accurate method of setting the hysteresis. One input of each
　　comparator is internally connected to the reference. The other
　　input is available externally, via an internal mux, through pins
　　±INA_U or ±INA_L. The state of the output determines which
　　of these pins is connected at any one time.
　　The comparator outputs are open-drain with the output stage
　　sinking capability guaranteed greater than 5 mA over temperature.
　　The ADCMP341 has noninverting inputs and the ADCMP343
　　has inverting inputs. The devices are suitable for portable,
　　commercial, industrial, and automotive applications.
