555 Timer Schematic Diagram. 555 timers are very popular in electronics. Then the bistable 555 timer is stable in both states high and low.
The above circuit diagram is for the 1 minute timer circuit. This 555 timer circuit will remain in either state indefinitely and is therefore bistable. The threshold input pin 6 is connected to ground to ensure that it cannot reset the bistable circuit as it would in a normal timing application.
Additional timing from microseconds through hours terminals are provided for triggering or resetting if operates in both astable and monostable modes desired.
8 power or vcc pin 1. Then the bistable 555 timer is stable in both states high and low. 555 timers are very popular in electronics. This pin has no special function what so ever.
