LM393DR
Brand: Texas Instruments
The LM393DR is TI's commercial-grade version of the industry-standard dual comparator, packing two independent open-collector comparators into an 8-pin SOIC. A 2 V to 36 V supply range and 2 mV typical offset voltage make it a proven, widely second-sourced choice for general-purpose threshold detection in 0°C to +70°C environments.
