Part Number: SN74LVC2T45

Dear team

The customer would like to check the number arrangement of device marking.

Form datasheet page 20. The device marking of SN74LVC2T45DCUR is CT2X.

1. From top of package, the number arrangement of device marking is Q3,Q1,Q2,Q4?

2. Q3=C,Q1=T,Q2=2,Q4=Z, Is device marking CT2Z as below picture?

Many thanks

The quadrant information applies to the orientation in the tape. But your photo does not show a device in the tape. Forget about quadrants.

The marking is printed so that it is readable in the usual way (lines top to bottom, letters left to right) when pin 1 is a the bottom left.
(Page 30 of the datasheet shows the pin 1 index area. In the photo, the white bar is at the left, so pin 1 is a the bottom left.)

The marking of this device is T2 CZ.
