CD4013B: ON/OFF Issue

Part Number: CD4013B

Dear Ti,

I have been using CD4013 to control ON & OFF of a specific device. The turning OFF/ON is created by giving a positive edge voltage trigger at the clock pin of the IC. The output of the Q bar is connected to the D input, reset is grounded. This logic is working fine for most of the devices.

In some specific cases, the voltage at the clock pin is drifting which is causing the device to automatically ON/OFF. Can you please explain me the happenings of this?

Thank You,

With Regards,

Raahul Bharadwaj
