There is no difference.

In particular, neither is available on the market right now, so buying them from a non-authorized dealer is likely to result in counterfeit or recycled devices.

Hi, No Difference in the sense, Same Form-Fit- Function ? as well as same Terminal finish / ESD (HBM) / MSL rating ?

we can see that there are 2 separate datasheet available. If u have any PDN document for this part. please share here.

and also I can see the operating temperature is different. kindly check.

They are literally the same chips.

There is a single datasheet.

these are the 2 datasheet we got. here the operating temperature is differ. can u please check which one is correct MPN and valid part.

Please confirm.

Apparently, the SN74HC244QDWRG4Q1 got associated with the wrong datasheet. It actually is a -Q1 device.

Please correct that issue. Thank you. Then can we consider the both MPNs are same Form-Fit-Function ?

They are identical.

Hi Ganesh,

Please report the issue using the link on the datasheet and we will add it to our log. Both MPNs are exactly the same as Clemens indicated.

Best,

Malcolm
