Note 1: Test pins TE1, TE2 and TE3 must be left floating.

Note 2: XCLR pin can be left unconnected when not used. It has internal pull up to VDD.

Note: On PCB the exposed pad is recommended to be connected to GND. It could be also left floating but it cannot be connected to any

other potential than GND.
