Could you help to suggest GPIO 1.8V to 3.3V Level shifter (bidirectional) products

Thanks

Hi Gareth,

The AXC selection is a good recommendation for GPIO. You may also see below for additional recommendations if higher bit counts are needed, thanks.

Best Regards,

Michael.

Hi Michael

Are there any concer if using TXS0108E?

It is more convenient to have automatic-DIR control.

TXS translators have many restrictions (open-drain outputs, no pull-down resistors, cannot drive capacitive/inductive loads, limited speed). This might or might not matter in your application.
