Texas Instruments NE556/SA556/SE556 Dual Precision Timers Datasheet
The NE556, SA556 and SE556 are dual precision timer ICs that contain two independent timing circuits similar to the classic NE555 design. Each timer can be configured for astable (free‑running) or monostable (one‑shot) operation using external resistor‑capacitor networks, and the timing can be adjusted via the control‑voltage input.
The document lists the electrical characteristics, absolute maximum ratings, recommended operating conditions, package options, and application information for the three device variants, along with safety notices and warranty statements from Texas Instruments.
