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 of
Vdd 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.
