    Cool Input buffer

    Hi,

    I'm creating an application that reads the state of 4 relays (NO contacts) to PortA0 - 3 of a Pic16F876A.
    I was wondering whether I need to implement a buffer circuit to shape the input pulse or not.
    Attached is an example of the buffer.

    Thanks.

    Best regards
