Note: Because the substrate of the die is internally connected to GND, the die has to be connected to GND or

left floating. Please make sure that GND is the first pad to be bonded. Pick-and-place and all component

assembly are recommended to be performed in ESD protected area.

Note: Pad coordinates are measured from the left bottom corner of the chip to the center of the pads. The

coordinates may vary depending on sawing width and location, however, distances between pads are accurate.

Note: Test Multiplexer Output is for testing only and must not be connected in module.
