(1) constitute a Schmitt trigger, used for the interface of the TTL system, shaping circuit or pulse amplitude correction;
(2) constituting a multivibrator to constitute a signal generating circuit;
As shown on the right,
Oscillation period: T = 0.7 (R1 + 2R2) C [2]
(3) constitute a one-shot trigger for timing delay shaping and some timing switches.
The 555 application circuit can be combined into one or more of these three methods to form various practical electronic circuits, such as timers, frequency dividers, pulse signal generators, component parameters and circuit detection circuits, and toy game machine circuits. , audio alarm circuit, power exchange circuit, frequency conversion circuit, automatic control circuit, etc.
