The output type supports CMOS, MOS, TTL, and open-collector logic levels — so the comparator interfaces directly with a downstream microcontroller GPIO or a discrete logic gate without a level shifter. TI lists the LM2901DRE4 with active product status.","metaTitle":"LM2901DRE4 Quad General-Purpose Comparator, -40°C to 125°C","metaDescription":"TI LM2901DRE4 quad comparator in 14-SOIC, 2V to 30V supply, 20mA output, -40°C to 125°C.
