Description

The LM555 is a highly stable controller capable of pro-

ducing accurate timing pulses. With a monostable opera-

tion, the delay is controlled by one external resistor and

one capacitor. With astable operation, the frequency and

duty cycle are accurately controlled by two external

resistors and one capacitor.
