General Description
The NE555 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 re-
sistor 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
circuit may be triggered and reset on falling waveforms, and
the output circuit can source or sink up to 200mA or drive
TTL circuits.
Features
n Direct replacement for SE555/NE555
n Timing from microseconds through hours
n Operates in both astable and monostable modes
n Adjustable duty cycle
n Output can source or sink 200 mA
n Output and supply TTL compatible
n Normally on and normally off output
Applications
n Precision timing
n Pulse generation
n Sequential timing
n Time delay generation
n Pulse width modulation
n Pulse position modulation
n Linear ramp generator
