ELM742xxC CMOS Low power voltage comparator

http://www.elm-tech.com■General description

ELM742xxC is a low voltage and low power comparator which can input and output signals in full range ofVdd to Vss. ELM742xxC can operate with single power source and low voltage supply (operating voltage range: VDD≥1.0V) condition. ELM742xxC provides 2 kinds of output style: N-ch opendrain and CMOS output.

■Features■Application• Low voltage operation: Vdd≥1.0V• Low current consumption : Typ.1μA(Vdd=3.6V, Vout=”Low”)
Typ.0.6μA(Vdd=3.6V, Vout=”High”)• Operating voltage range : 1.0V≤Vdd≤7.0V• Input voltage range: Vss to Vdd• Output stage: N-ch open drain or CMOS output• Package: SOT-25, SC-70-5(SOT-353)• Battery-operated devices• Micropower signal processing• Low voltage analog circuits■Maximum absolute ratings
