What are the key applications of the LM393?

It is used in limiters, pulse generators, square wave oscillators, A/D converters, and as a logic level interface for TTL, CMOS, and MOS systems.

What should engineers review before using the LM393?

Engineers should note that the output is an open-collector type, meaning an external pull-up resistor is required to pull the output high. Also, verify the input common-mode voltage range.

What are the key specifications of the LM393?

It features a 2.0mV max input offset voltage, 0.4mA supply current, and operates from 2V to 36V (single) or ±1V to ±18V (dual).

What is the sourcing status of the LM393?

The LM393 is an active, widely available component with high stock levels, making it a low-risk choice for long-term BOM planning.

What is the pinout of LM393?

Use the LM393 datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about LM393 pinout to locate pins, power rails, and interface signals before layout.
