Please refer the below image. Can I use CLR pin to reset the output pulse, but the CLR should not trigger the output pulse again?
Hi Ramesh,
You would need to coordinate the CLR input with one of the other inputs to prevent a trigger after clearing the output.
I marked the trigger input with a blue T above.
When CLR\ is forced LOW, the device is immediately reset, turning off the output pulse.
If A\ is LOW and B is HIGH, then switching CLR\ back HIGH will trigger an output.
If either A\ is HIGH or B is LOW, then switching CLR\ back HIGH will not trigger an output.
From your diagram (figure 8 in the Nexperia datasheet),
The rising edge on CLR\ marked (1) would not trigger an output pulse because B is LOW, disabling the trigger input to the device.
The rising edge marked (2) would cause a trigger because B is HIGH, enabling the trigger input.
In other words - our device works the same as the Nexperia device.
