The NE556N from Texas Instruments is a dual monolithic timing circuit capable of producing accurate time delays or oscillations. It operates in both astable and monostable modes, controlled by external resistor-capacitor networks. Each timer features a trigger level at approximately one-third of the supply voltage and a threshold level at approximately two-thirds of the supply voltage, which can be adjusted via the control voltage pin.
This dual timer IC supports a wide operating voltage range from 4.5V to 16V and can operate at frequencies up to 100kHz. The output structure is capable of sourcing or sinking up to 200mA, and it is TTL-compatible. The device exhibits a temperature stability of 0.005% per degree Celsius.
Packaged in a 14-pin DIP (Dual In-line Package), the NE556N is designed for through-hole mounting. It operates within a temperature range of 0°C to 70°C. The reset input overrides all other inputs and is used to initiate a new timing cycle. Tie all unused inputs to an appropriate logic level to prevent false triggering.
