NE555N

GENERAL PURPOSE SINGLE BIPOLAR TIMERS

• LOW TURN OFF TIME MAXIMUM OPERATING FREQUENCY
• GREATER THAN 500kHz .TIMING FROM MICROSECONDS TO HOURS OPERATES IN BOTH ASTABLE AND MONOSTABLE MODES HIGH OUTPUT CURRENT CAN SOURCE OR SINK 200mA
• ADJUSTABLE DUTY CYCLE
• TTL COMPATIBLE
• TEMPERATURE STABILITY OF 0.005% PERoC 

DESCRIPTION
The NE555 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. The circuit may be triggered and reset on falling waveforms, and the output structure can source or sink up to 200mA. The NE555 is available in plastic and ceramic minidip package and in a 8-lead micropackage and in metal can package version.
