NE555P Precision Timer

Regular price €0,20

Tax included.

The NE555P are precision timing circuits capable of producing accurate time delays or oscillation.
In the time-delay or monostable mode of operation, the timed interval is controlled by a single external resistor and capacitor network.
In the a stable mode of operation, the frequency and duty cycle can be controlled independently with two external resistors and a single external capacitor.
The threshold and trigger levels normally are two-thirds and one-third, respectively, of VCC.
These levels can be altered by use of the control-voltage terminal.
When the trigger input falls below the trigger level, the flip-flop is set, and the output goes high.
If the trigger input is above the trigger level and the threshold input is above the threshold level, the flip-flop is reset and the output is low.
