Part Number: CD4072B


Any refence design to use CD4072BM96 in a circuit.

    Logic devices are so simple that reference designs are usually not needed. Just add a decoupling capacitor, and ensure that all inputs have a valid voltage.

    What is the actual problem you're trying to solve?

    Hi Abinaya,

    Here's an example of how you might use the CD4072B in a circuit:

    I show 3 input signals (A, B, C) coming from a 10V digital device which are then logically OR'd together by the CD4072B.

    The output of the OR gate is connected directly to a digital input of a device that is operating at the same voltage.

    I terminated all the unused inputs of the CD4072B to ground, and left the unused output floating.

    Each digital device has its own 0.1uF bypass capacitor placed close to the supply pin.

    Can I be of further assistance, or does this resolve your question?
