NE556 Dual Timer IC

NE556 is a dual timer IC that is used for creating time delays or oscillations. It is a dual version of the 555 timer IC. The two timers inside this chip share the common ground and power supply but operate independently. It can operate in the astable or the monostable mode by only two external components. One resistor and capacitor (RC) are connected externally for providing timing control

NE556 Dual Timer Features

• A dual version of NE556 consists of two precision timers that operate in both monostable and astable modes.
• It is specified for operation from 4.5 V to 16 V.
• TTL compatible output which can source or sink current of up to 150mA.
• Adjustable duty cycle.
• It can produce a timing delay from microseconds to hours.
• The operating temperature range is from 0 to 70 degrees Celsius.
• It has temperature stability better than 0.005% per C.
