TCA6418E: Set pin to high Z

Will Wang47

Part Number: TCA6418E

Tool/software:

Hi team,

Customer plan to use TCA6418 in their project. To minimize the leakage, they plan to set the pin to high Z status. Could you help check they could do this?

Thanks and Best Regards,

Will

The only way to get an I/O pin in the Hi-Z state is to configure it as an input. Please note that it still needs to have a valid logic voltage (low or high) applied to it, so you should enable a pull-up/-down, or connect it externally.

Hi Will,

I concur with Clemens feedback. Please note the device will by default set all GPIOs to input with 50KOhm pull downs.

Regards,

Adam
