打算用THS6214做一个设计，对Datasheet中的某些描述有些疑惑，特提出向各位高人请教。
第3页对PowerPad有如此描述：
(1) The PowerPAD is electrically isolated from all other pins and can be connected to any potential voltage range from
VS– to VS+. Typically, the PowerPAD is connected to the GND plane because this plane tends to physically be the
largest and is able to dissipate the most amount of heat.
但是在BOARD LAYOUT GUIDELINES部分（第31页），却是这样说的：
两处的说法似乎有些矛盾。如果用±12V供电，PowerPad能接GND吗？
