Product Overview
The LM393PT from STMicroelectronics is a low-power, dual-channel voltage comparator designed for general-purpose applications. It operates from a single power supply over a wide voltage range of 2V to 36V (or ±1V to ±18V for dual supplies) and features low supply current (0.4 mA typical per comparator). The open-collector output allows wired-AND connections and interfaces with various logic families. Housed in a compact 8-TSSOP package, it is ideal for space-constrained designs.
