LTM2881IV-3?

I bought the LTM2881IV-3 (in an offline market).
I checked the pin before using it and it was different from the datasheet as shown in the picture on the right.

 


In the data sheet, pins B1 to B5 are connected to GND, and pins B6 to B8 are connected to VCC.
And K1 to  K8 are connected to GND2.
However, I have confirmed that the chips B1 and B2 are independent of each other.
B3 to B5 were connected and B6 to B8 were connected.
Also, K1, K2 and K3 are independent from each other and K4 to K8 are connected.

 

Is the LTM2881IV-3 product right?
I am worried about using it differently from datasheet pinmap.
If the LTM2881IV-3 is correct, where are the B1, B2, K1, K2, and K3 pins used?
