CD4053B question

Other Parts Discussed in Thread: CD4053B

Hi Team,

In CD4053B datasheet p.9,

what does any channel mean?

what difference between common out/in and any channel?

both data are difference.

Thank you in advance!!

    Hi Jason ,

    The COM channel refers to the common channel or the input port and any channel would refer to A or /A channels as shown here below :

    This was meant to be like a common statement encompassing the other 2 devices of the family which explicitly state the COM channel . It is little different in the case of CD4053B though.

    Hi sir,

     

    Thank you for your reply, but I still don't understand.

    Any channel mean the BW of all channel is 60db, but common channel mean only one channel. Am I right?

    in addition, customer want to ask the condition below if it is workable.

    1. Send 5-10MHz signal via CD4053B

    2. The amplitude of this signal is around 4V

    3. channel to channel switching frequency is 10kHz 

    4. VDD (V)=5V. (I think VDD should be 10V)

     

    thank you in advance!!

    BR,

    Jason

    Hi Jason ,
    Common channel means channel at which input is sent and other channel will be the output . CD4051 has 1 COM channel , CD4052 has 2 COM channels , CD4053 has 3 COM channels .
    1) Yes , CD4053B can handle 5-10MHz at 4V with the Vdd you specified .
    What do you mean by channel to channel switching frequency ?

    Hi ShreyasRao,

    The block diagram of their application is shown in below. it looks they used x/y channel as input and then x or y as output. they want to switch ax/ay channel as 10kHz by A, B, C pin. Is it workable?

    Yes , CD4053 Mux is bidirectional and you are within the switching frequency limits .
