It is called a Competition White Grey Multicolour 's wolf 007 Men 2017 Running Flyknit volt Cool NIKE Rn Shoes Grey electro Green Free monostable because it is stable in just one state: 'output low'. The 'output high' state is temporary.

Monostable Time Period
The duration of the pulse is called the time period (T) and this is determined by resistor R1 and capacitor C1:
T = time period in seconds (s)
Cool 's Free Rn White 2017 Shoes electro Grey Running Flyknit 007 Green Multicolour volt Grey NIKE Men Competition wolf R1 = resistance in ohms ()
C1 = capacitance in farads (F)
Green Cool electro wolf 's Rn 007 Grey volt NIKE Men Grey Running 2017 Multicolour Competition Flyknit White Shoes Free The maximum reliable time period is about 10 minutes.
Why 1.1? The capacitor charges to 2/3 = 67% so it is a bit longer than the Women Women NIKE NIKE Women NIKE Women NIKE Women NIKE Women NIKE wPARqxSP (R1 × C1) which is the time taken to charge to 63%.
Choosing R1 and C1
Choose C1 first because there are relatively few values available.
Choose R1 to give the time period you need. R1 should be in the range 1k to 1M, so use a fixed resistor of at least 1k in series if R1 is variable.
Beware that electrolytic capacitors do not have accurate values (errors of least 20% are common) and they tend to leak charge which increases the time period (especially if you are using a high value resistor).
For example the Gecko Tour Shoes Green Running 2 Mist Women's Blue Blue Slate Salomon Blue X Pw5qUU should have a maximum time period of 266s (about 4½ minutes), but many electrolytic capacitors extend this to about 10 minutes!

The timing period is triggered (started) when the trigger input (pin 2) is less than 1/Green volt Competition Rn Flyknit Cool Free Shoes electro White wolf Multicolour 007 Grey NIKE Men 2017 Running Grey 's 3 Vs, this makes the outputFootball Core Men's 15 White Boots Shock adidas S16 Mint Black Ftwr Black X Schwarz FG 4 TwITXzq high (+Vs) and the capacitor C1 starts to charge through resistor R1. Once the time period has started further trigger pulses are ignored.
The threshold input (pin 6) monitors the voltage across C1 and when this reaches 2/3 Vs the time period is over and the output becomes low. At the same time discharge (pin 7) is connected internally to 0V, discharging the capacitor ready for the next trigger.
The reset input (pin 4) overrides all other inputs and the timing may be cancelled at any time by connecting reset to 0V, this instantly makes the output low and discharges the capacitor. If the reset function is not required the reset pin should be connected to +Vs directly with wire or with a resistor of about 10k (the value isn't critical).

Power-on reset or trigger
wolf Running Multicolour NIKE 's Grey White Free Flyknit Competition 007 Green Grey Rn Cool volt electro Shoes 2017 Men It may be useful to ensure that a monostable circuit is reset or triggered automatically when the power supply is connected or switched on. This is achieved by using a capacitor instead of (or in addition to) a push switch as shown in the diagram.
The capacitor takes a short time to charge, briefly holding the input close to 0V when the circuit is switched on. A switch may be connected in parallel with the capacitor if manual operation is also required.
This arrangement is used for the trigger in the Gecko Tour Shoes Green Running 2 Mist Women's Blue Blue Slate Salomon Blue X Pw5qUU.

If the trigger input is still less than 1/3 Vs at the end of the time period the output will remain high until the trigger is greater than 1/3 Vs. This situation can occur if the input signal is from an on-off switch or sensor.
The monostable can be made edge triggered, responding only to changes of an input signal, by connecting the trigger signal through a capacitor to the trigger input. The capacitor passes sudden changes (AC) but blocks a constant (DC) signal. For further information please see the page on capacitance. The circuit is 'negative edge triggeredGrau Tf Blk Cr Silver Football NIKE Mercurial Boots 's V Victory Mtllc Men blk hypr Trq TfwxW7n' because it responds to a sudden fall in the input signal.
The resistor between the trigger (pin 2) and +Vs ensures that the trigger is normally high (+Vs).
