NVT2006

Hi,

In my current design i am planning to use NVT2006 to do the Level translation between

1. 1.2V to 1.8V

2. 1.5V to 1.8V.

Max operating speed is for SPI around 10MHz. Are there any concerns in this regard.

Regards,

Sudarshan

Hi Sudarshan,

1. OK

2. I am afraid this will not work properly. The minimum voltage difference between the VCC(B) and VCC(A) is 0.6V.

BR, Tomas

Hi Tomas,

Sorry for replying late as i didnot get the alert.

Thanks for your feedback. In data sheet there is table which shows the PU's to be used b/w 1.5V to 1.8V . Am i missing something here? Please clarify

Regards,

Sudarshan

Hi Sudarshan,

The tables you are referring to are inaccurate. The NVT2006 is about 14 years old IC and I do not know who designed this part and created these pull up tables. We will need to correct them in the datasheet, but it will take some time.

Best regards,

Tomas
