ELM743xxA CMOS Low power voltage dual comparator
http://www.elm-tech.com■General description

ELM743xxA is a low voltage and low power dual comparator which can input and output signals in full rangeof Vdd to Vss. ELM743xxA can operate with single power source and low voltage supply (operating voltage
range:Vdd≥1.2V) condition. ELM743xxA provides 2 kinds of output style: N-ch opendrain and CMOS output.

■Features■Application• Low voltage operation: Vdd≥1.2V• Low current consumption : Typ.2μA(Vdd=3.6V, VoutA=VoutB=Low)
Typ.1.2μA(Vdd=3.6V, VoutA=VoutB=High)• Operating voltage range : 1.2V≤Vdd≤7.0V• Input voltage range: Vss to Vdd• Output stage: N-ch open drain or CMOS output selectable• Package: WSON8-2×2, SON8-3×3• Battery-operated devices• Micropower signal processing• Low voltage analog circuits■Maximum absolute ratings
