LM556M/TR

This device integrates two independent 555 general-purpose timer circuits. The two circuits share the power supply (VCC) and ground (GND) pins, while all other circuitry and pins are fully independent of each other. Each timer circuit consists of six functional blocks: a threshold comparator, a trigger comparator, an RS flip-flop, a reset input, a discharge, and a trigger input. Each circuit supports precise timing or oscillation waveform generation through external resistors and capacitors.

Applications

• Precision timing
