Voltage Comparator
ELM74x series is low voltage and low comparator which is designed for the application of battery-operated devices. ELM742xxC is single CMOS comparator while ELM743xxA is dual comparator. Both of them provide 2 kinds of output style: N-ch open drain and CMOS output. ELM74x series is able to extend battery life because of its single power source, low voltage supply operating and low power consumption.
