The LM393 is an electronic part manufactured by KEXIN and it is an analog comparator in an 8-pin SOP package. It is RoHS compliant and is commonly used in the design of comparator circuits for various applications such as voltage detection, temperature detection, pressure detection, etc. It has two inputs, one inverting and one non-inverting, and an open-collector output. The IC is designed for comparator-based supervisory functions and can be used for voltage detection, temperature sensing, and more. It operates over a wide range of supply voltages with low input current and high output current. It has protection against latch-up, and is hysteresis-controlled for improved noise performance. This part is RoHS compliant and is suitable for industrial temperature applications.
