PCA9518: I2C HUB Chip

GARETH OU
Guru 11415 points
Part Number: PCA9518
Other Parts Discussed in Thread: TCA9548A, PCA9548A

Hi 

We are seeking the I2C HUB chip having at least 5 Port-out for Android platform. I just found PCA9518PWT. I am checking its feasibility.

 

Could you help provide your feasible chips’ respective model name, datasheet and quotation?  Many thanks!!

    What exactly do you mean with "hub"? The PCA9518 buffers its upstream port and its four downstream ports; it is used when the total bus capacitance would exceed 400 pF (or whatever the drive strength of your devices is). If you just want to disable certain bus segments, you can use an I²C switch like the PCA9548A/TCA9548A.

    Hi Gareth,

    By respective model name, are you wanting the CAD footprint or PSPICE model? We don't have PSPICE models. CAD models can be found on the product portfolio here. I suggest going with PCA9518PWR since the other package options are in the "last time buy" phase. 

    Datasheet is here. 

    Orders can be fulfilled on the product portfolio page towards the bottom of the page. 

    Regards,

    Tyler
