PCA9306: Can PCA9306 support 8MHz ?

Mercy Chou

Part Number: PCA9306
Other Parts Discussed in Thread: LSF0102

Tool/software:

The main chip works at 8MHz, and we’d like to use PCA9306 for the level shift function. Can PCA9306 works at 8MHz as well?

Thanks

Hi Mercy,

Is it possible to switch to LSF0102 which supports the required data rate at 8 MHz from a datasheet perspective?

Regards,

Tyler

Hi Tyler

Thanks for your recommendation.

We have PCA9306 stock that we’d like to leverage.

If the data rate couldn't reach 8MHz, then we will redesign.

Looking forward to your confirmation.

Best regards,

Mercy

Hi Mercy,

From a datasheet perspective, I cannot confirm that the PCA9306 will work at 8 MHz although the device may be designed for data rates much higher.

Either use PCA9306 at 8 MHz without support from its datasheet, or switch to LSF0102 which is capable from a datasheet perspective.

Regards,

Tyler
