CMOS Low power voltage dual comparator
ELM743xxA
Preliminary
■General description
ELM743xxA is a low voltage and low power dual comparator which can input and output signals in full range
of 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.
