TS3A5017: TS3A5017 N type or P type question

Part Number: TS3A5017

We have a question about the TS3A5017 SP4T analog switch.

(1)   The following chart’s MOSFET is N type or P type?

(2)   See following chart, the “D” means “MOSFET’s Drain terminal” or not

(3)   See following chart, the “S1, S2, S3, S4” means “MOSFET’s Source terminal” or not

(4)   Our design is the GND will connect to “D(common path)”, and the power source connect to “S1, S2, S3, S4”. Is it ok?

  • AJ,

    (1)   The following chart’s MOSFET is N type or P type?

    The chart you attached above is an abstracted diagram and is not the complete representation of the IC design.  The switch architecture is a transmission gate which is both N type and P type in parallel. 


     

    You can tell the architecture of any switch, N type or P type from the on-state resistance vs input voltage.  The input voltage changes the Vgs of the FET and you can see the resistance of the FET as the Vgs varies across input voltage.


     

     

     

    (2)   See following chart, the “D” means “MOSFET’s Drain terminal” or not

    Yes,  you can interpreted D to mean Drain terminal.  The switches are bidirectional and either terminal can be an input or output.  

     

     

    (3)   See following chart, the “S1, S2, S3, S4” means “MOSFET’s Source terminal” or not

    Yes,  you can interpreted S to mean Source terminal.  The switches are bidirectional and either terminal can be an input or output.  

     

     

    (4)   Our design is the GND will connect to “D(common path)”, and the power source connect to “S1, S2, S3, S4”. Is it ok?

    The switches are bi-directional and you can connect the terminals in either direction.  Why would you short a power supply to ground through the switch?  There is concern how much current you can pass through the switch.  The limit is stated in the absolute maximum rating table.
