LM393N/NOPB

The LM393N/NOPB from Texas Instruments is a dual general-purpose comparator designed for a wide range of applications. It features two independent comparator channels, each with an open-collector output compatible with various logic systems including TTL, DTL, ECL, MOS, and CMOS.

This comparator operates with a wide supply voltage range from 2V to 36V, making it suitable for diverse power configurations. It offers a low supply current drain of 0.4mA, independent of the supply voltage, which is beneficial for battery-powered applications. The device boasts low input bias current and low input offset current, along with a maximum offset voltage of 5mV at 25°C.

The LM393N/NOPB has a propagation delay time of 700ns and an operating temperature range of 0°C to 70°C. It is available in an 8-PDIP (0.300", 7.62mm) package, designed for through-hole mounting. The output type is open-collector, and it supports both single and dual supply operations.

Key electrical characteristics include a typical supply current per channel of 0.2mA, a maximum input bias current of 250nA, and a maximum offset voltage of 3mV. The input common-mode voltage range includes ground, and the differential input voltage range is equal to the power supply voltage. Its low output saturation voltage of 250mV at 4mA ensures efficient operation.
