ELM742B
Low voltage comparator
■General description
ELM742B is low voltage and low power CMOS comparator which makes it easy to design power circuits;
ELM742B is able to extend battery life because of single power source, low voltage supply operating range (Vdd
≥+1.0V) and low power consumption also.
With N-ch open drain output, ELM742B is able to introduce depletion transistors to differential input stages
and drive TTL and CMOS logic IC. ELM742B also covers wide input voltage range (Vss+0.1V to Vdd-0.2V).
