Description
LM555/NE555 is a highly stable controller capable of pro-
ducing accurate timing pulses. With monostable operation,
the time delay is controlled by one external and one capac-
itor. With astable operation, the frequency and duty cycle are
accurately controlled with two external resistors and one
capacitor.
