Monostable Multivibrator Circuit Diagram with Output Pulse 0.5-300 ms Discrete

A monostable multivibrator circuit produces a fixed pulse-width when the input is triggered. First, the input is given to CR1. Since the TR1 would short the input to ground during the active state appear on the output, this diode should be an open collector. The output from this circuit is tapped from TR2′s collector. The output pulse width of this schematic is varied between 0.5 to 300 ms. This output pulse can be adjusted by a 1M trimmer potentiometer R5. For more details, here is the schematic diagram :
