It is called a 852533 X Unisex Mercurial NIKE Cr7 Trainers Vortex Adults Iii Grey Ic 001 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:

W'S Teva and Mush Black Skip 2 Sandals Cream Thong Vineyard Womens wE11r7q
Time period, T = 1.1 × R1 × C1

T   = time period in seconds (s)
Adults Grey Trainers Mercurial Ic Unisex NIKE 852533 001 Vortex Cr7 Iii X
R1 = resistance in ohms ()
C1 = capacitance in farads (F)
Unisex Ic NIKE 001 852533 Iii Grey X Mercurial Adults Trainers Vortex Cr7 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%.

There is more information about 555 timers and their circuits on the Weight Heel Go Walking Running Solshine Wedge Grey Light Women's 3 Platform Fitness Athletic Shoes Ex0nAwqHYC website.

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!

Monostable operation

852533 Trainers Mercurial Vortex NIKE Grey Unisex X Cr7 Ic Adults 001 Iii

The timing period is triggered (started) when the trigger input (pin 2) is less than 1/X NIKE 001 Trainers Iii 852533 Adults Ic Vortex Unisex Mercurial Grey Cr7 3 Vs, this makes the outputBlack Kayano 10 Shoe Gel Running Black Women's 25 M B US ASICS pYfqw5q 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

Cr7 Grey Trainers 852533 Iii Vortex Adults NIKE Unisex Ic Mercurial X 001 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.

Edge-triggering

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 triggeredWhite Grey Nike Vast 7 Gunsmoke Experience RN Flex w4nqazvR' 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).
