CD4053B: Vee and Vss definition of CD4053B

Part Number: CD4053B
Other Parts Discussed in Thread: TS12A12511

Hello,


I have a question on the CD4053B part - I see that it uses the voltages, Vee (Negative power input) and Vss (Ground). In what circumstance would Vee be used?

Thanks,

Andrea

    Andrea,

    The Vee pin gives you the option to operate the device in dual power supply systems.  This will allow you to pass a signal with negative signal swings through the CD4053B.  I these different configurations below you can pass a signal ranging from Vee to Vdd

    What type of project are you working on?  I maybe able to help you find the right switch.  

    Thank you,

    Adam

    Hi Adam,

    I'm trying to take an analog signal, which indicates a voltage value from 0-12V, and output it to one of two plates which will help to control particle movement. Pretty much I need a demux device with just one device - but if there's three, I was just going to tie the other two to ground. Would the CD4053B be the best device for this? Also if so, which would be the best configuration in terms of dealing with Vee and Vss for this?

    Thanks,
    Andrea

    Andrea,

    If you only need to take one 0-12 V signal from one path to two different places I would recommend using the TS12A12511.  I found this device using the TI.com signal switch selection tool and filtered for 1:2 switches that can support up to 12V. 

    To use the TS12A12511 to support analog signal from 0-12V you would connect the GND pin and V- pin to GND (0V) and 12 V to the V+ supply pin.

     

    The TS12A12511 is also a higher performing signal switch so you will have less signal distortion. 

    Thank you,

    Adam
