<p>A display protection circuit includes a first OR gate which receives a first pulse at one input and a first clock signal at another input. A second OR gate receives the first pulse at one input and a second clock signal at another input. A first monostable multivibrator is coupled to the first OR gate and receives an output of the first OR gate and generates a second pulse in response thereto. A second monostable multivibrator is coupled to the second OR gate and receives an output of the second OR gate and generates a third pulse in response thereto. A first logic gate is coupled to the first and second monostable multivibrators and generates a fourth pulse which changes state in response to one of the first and second clock signals stopping transitioning for a first predetermined period of time.</p> |
