Monostable Using the 4027 (CB131E)

A configuration like the one used with the 4013 is also suitable for the 4027. The amount of time the output is “1" after the circuit is triggered is about 0.7 x R x C. R1 must be at least 5 times larger than R in this circuit. The diode is any generaI-purpose type, such as the 1N4148 or 1N914. The circuit is shown bellow. It is triggered by the positive transition of the input signal the 4027 is a Dual J-K Master/Slave Flip-Flop with Set and Reset.
