VOH / VOL of PCA9617A

[Jacky_L]

Hi,

For PCA9617A, there is side A and side B. 

My side A is 1.8V, side B is 3.3V

But test conditions for Vcc=2.2V. 

I would like to know VOH / VOL of SCL /SDA.

Could you give me some advice?

Hi

Yes, I saw VOL in datasheet, but  the test conditions is for Vcc=2.2V.  and my Vcc is 3.3V

So, I would like to ask about VOL of 3.3V.

thanks,

Jacky

Hi Jacky,

please refer to the notes on the top of the Table 5. The data are valid for VCC(A) = 0.8V to 5.5V and VCC(B) = 2.2V to 5.5V. For the 3.3V, you can expect, that the VOL value will be closer to the maximum VOL value, than for the 2.2V, but still within the boundaries. 

With Best Regards,

Jozef

Hi Jacky,

for the VOL values for both A and B sides, please refer to the Table 5. in the PCA9617A datasheet. 

The VOH value is VDD-0.4V.
