Functional description

[1]

H = HIGH voltage level; L = LOW voltage level

(1) This is not a supply pin. The substrate is attached to this

pad using conductive die attach material. There is no

electrical or mechanical requirement to solder this pad.

However, if it is soldered, the solder land should remain

floating or be connected to GND.
