LM555CM - Timer

Download the LM555CM datasheet PDF. This datasheet also covers the LM555 variant, as both devices belong to the same timer family and are provided as variant models within a single manufacturer datasheet.

General Description

The LM555 is a highly stable device for generating accurate time delays or oscillation.

Additional terminals are provided for triggering or resetting if desired.

In the time delay mode of operation, the time is precisely controlled by one external resistor and capacitor.

Key Features
