PCA9509: VIL 0.15V is too low for my application, any option with higher VIL?

Hi Team,

Originally, I would like to use PCA9509 as voltage translator of 5V<-->3.3V, but when I checked the details, I found VIL of PCA9509 is 0.15V, which is too low for slave 6# in below schematic.

Can you kindly recommend an option with higher VIL? For example, 0.8V or higher. 

Thank you.

Kind Regards,

Boler

It's great, thanks.Re: PCA9509: VIL 0.15V is too low for my application, any option with higher VIL?

HI Boler：

You can refer to below:

Thanks for the quick update.
I also notice a similar part PCA9306 as NTS0102 , any difference?

Hi Boler

If only for  level translating we have lots:

NVT2002.NTS0102:

Voltage Level Translators (Level Shifters) | NXP Semiconductors

NTS0102 | NXP Semiconductors

Hi Guowei,

I use PCA9509 only for level translating, so I would like to change PCA9509 to a common voltage-level translator, such as TI TCA39306. Can you please advise NXP option in place of TI TCA39306? Thank you.

Kind regards,

Hi Boler

You can consider about PCA9617!
