LM393PE3 TI Low-Power Dual Comparator | 8-PDIP | 2-36V Supply, Open-Collector Output

Product Overview

The LM393PE3 is a low-power, dual voltage comparator from Texas Instruments (TI) designed for applications requiring low supply current and wide supply voltage range. Housed in an 8-pin PDIP package, this device features two independent comparators with open-collector outputs, making it suitable for interfacing with various logic families. The LM393PE3 operates from a single power supply over a wide range of 2V to 36V (or dual supplies ±1V to ±18V) and draws a typical supply current of only 0.4mA per comparator. Its low offset voltage (typically 2mV) and high gain (200V/mV) ensure accurate comparisons. The device is characterized for operation from 0°C to 70°C.
