LM556 - Dual Timer

LM556 Dual Timer IC - High-Stability Timing Controller

The LM556 Dual Timer IC is a highly stable and versatile integrated circuit designed for precise timing applications. It functions as a dual 555 timer, offering two independent timing circuits within a single package. This controller is capable of generating accurate time delays or continuous oscillations. Timing for each function is easily set using external resistors and capacitors. The LM556 supports both astable and monostable operating modes. Its outputs can sink or source up to 200mA, making it suitable for driving various loads. Both the output and supply are TTL compatible, ensuring easy integration into digital systems. This IC is an ideal choice for pulse generation, sequential timing, and modulation applications.
