    Hello Pooja,
    You have given me zero information about your system. In order to determine what is wrong, I would need at least some details regarding the use of the part. I could help to troubleshoot if you can provide:

    (1) System schematic
    * To be useful, this must include all external connections to ICs, cables, headers, connectors, etc.

    (2) Input/output scope captures
    * Must be on the same scope shot. If not enough channels are available, one channel should stay on a reference signal to match all signals later.
    * It is also helpful to include the supply and ground signals at the device.

    (3) Expected behavior
    * What exactly are you trying to achieve with the device? This may seem like a silly question for a logic gate, but it is necessary since our devices are often used for non-standard applications due to their low cost and relatively simple internal structures.

    With the above 3 items, I can review the application and see if there are any issues.
