Other Parts Discussed in Thread: PCA9306

Hello

Generally, the open-drain circuit can support max data rate should be smaller than 10M, but in our PCA9306 datasheet, it show that this part can support to >100MHz. Can you give some comments? thanks

Regards,

Nanfang

    Hi Nanfang,

    Since PCA9306 is can be simplified as a simple switch, it is possible to support > 100MHz. However, this is heavily dependent on the loading settings in the setup.

    Another thing to keep in mind is that the -3db point does not mean how fast it can handle digital signals.

    Thanks,
