DEVICE FOR PREVENTING CONTACT BOUNCE

The proposed device for preventing contact bounce contains a D trigger and a blocking pulse former. The signal input of the trigger is used as the input of the proposed device, and the outputs are used as the outputs of the device. The blocking pulse former contains two monostable multivibrators with inverse start signals and an OR logic element. The inputs of the logic element are accordingly connected to the outputs of the monostable multivibrators, and the output is connected to the timing input of the trigger. The advantage of the proposed device is its enhanced reliability due to the increased slope of pulse edges and the extended range of the allowable values of used pulse and logic circuit elements.
