SN74LVC2G74-Q1: max Ioff current at the 25°C and 85°C

Hi Dylan,

When the customer test the Ioff at 25 and 85, they are smaller than 10uA.

Thanks & Best Regards,

Hi Sherry,

Yes, that's what "maximum" means. When they measure the value, it will be less than the maximum, guaranteed.

Hi Emrys,

My customer needs to make a theoretical calculation, this value can't exceed the specified value, which is required by the end customer.

 But now the theoretical value doesn't meet the requirement. 

In my understanding, if the temperature is lower, the Ioff current should smaller, right? How do we get the the value of 10uA? Could you please tell me the process? In the test, different device's Ioff is different, and they will have a max value-10uA, so we write the max value is 10uA, right? Then when you test it, at the different temperature, the test results are the same? The max value are all 10uA?

Thanks & Best Regards,

Sherry

Hi Sherry,

If 10uA doesn't meet the customer's requirement, then they should redesign their system. We do not guarantee any other value, and it's poor system design to use any other value than the max since the manufacturer (ie TI) won't guarantee that performance.

The maximum value is across PVT (process variations, voltage variations, and temperature variations).  This is the worst case possible value, plus some headroom to protect TI.  We do not characterize each temperature separately, nor do we guarantee them separately.
