18 V Supply Voltage, 0 to +70°C Storage Temperature, General Purpose Dual Bipolar Timers
Low turn off time
Adjustable duty cycle
TTL compatible
Timing from microseconds to hours The NE556 dual monolithic timing circuit is a highly stable controller capable of producing accurate time delays or oscillation in the time delay mode of operation, the time is precisely controlled by one external resistor and capacitor for a stable operation as an oscillator, the free running frequency and the duty cycle are both accurately controlled with two external resistors and one capacitor.
