LM556CM/NOPB General Description

The LM556CM/NOPB is a dual-timing circuit that is designed to generate accurate time delays or oscillations. It is a monolithic timing device that incorporates two independent 555 timer circuits in a single package. This device offers the same functionality as the popular NE556, but with improved specifications and precision.Each timer circuit in the LM556CM/NOPB can operate in either monostable or astable mode, providing flexibility for various applications. The timing elements of each circuit are composed of an adjustable resistor and capacitor, allowing users to set precise time intervals as needed. The LM556CM/NOPB features a wide supply voltage range of 4.5V to 16V, making it suitable for a variety of voltage levels.This device also offers low power consumption, making it ideal for battery-powered applications. The output voltage swing is rail-to-rail, allowing for compatibility with a wide range of systems. The LM556CM/NOPB is available in a small 16-pin SOIC package, making it easy to integrate into existing circuits.
