NE556DR-MS

The NE556DR-MS integrates two 556 general-purpose timer circuits. These two timer circuits share a common power supply (VCC) and ground (GND), while all other circuitry and pins are independent of each other. Each general-purpose timer circuit consists of six functional blocks: a threshold comparator, a trigger comparator, an RS flip-flop, a reset input, a discharge stage, and a trigger input. Each timer circuit can achieve precise timing or generate oscillating waveforms through externally connected resistors and capacitors.
