555 Timer Analysis

555 Monostable Multivibrator (One-Shot)

About this Activity

The purpose of this activity is to hone your skills and test your ability to analyze the operation of a typical monostable (one-short) multivbrator circuit.

You are given some pertenent values and asked to solve for others.

See the Legend if you need any help with the definition of terms used in this activity.

Instructions

Solve the problem on a separate sheet of paper.

Given:

R = 380 kW
C = 717.7 nF

Find:

t_w

Solution:

t_w = 300 ms

Hint:

t_w = 1.1RC

Legend

C = value of timing capacitor C in farads
R = value of timing resistor R in ohms
t_w = pulse width (duration) in seconds
