The NE555 Timer IC is a highly stable device for generating accurate time delays or oscillation. Additional terminals are provided for triggering or resetting if desired. In the time delay mode of operation, the time is precisely controlled by one external resistor and capacitor. For astable operation as an oscillator, the free running frequency and duty cycle are accurately controlled with two external resistors and one capacitor. The NE555 Timer IC may be triggered and reset on falling waveforms, and the output circuit can source or sink up to 200mA or drive TTL circuits. Specifications: Package/Case: DIP-8 Minimum Supply Voltage: 4.5V Maximum Supply Voltage: 16V Product Series: NE555 No. of Timers/Counters: 1 Operating Temperature Range: 0 ~ 70°C
