(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.

[1] The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.
[2] The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability.
[3] For SO20 package: above 70 C derate linearly with 8 mW/K.
For TSSOP20 package: above 60 C derate linearly with 5.5 mW/K.
For DHVQFN20 package: above 60 C derate linearly with 4.5 mW/K.

[3] This is the bus hold overdrive current required to force the input to the opposite logic state.
[4] This parameter is valid for any VCC between 0 V and 1.2 V with a transition time of up to 10 ms. From VCC = 1.2 V to VCC = 3.3 V 0.3 V
a transition time of 100 s is permitted. This parameter is valid for Tamb = 25 C only.

ICC is measured with outputs pulled to VCC or GND.
[6] This is the increase in supply current for each input at the specified voltage level other than VCC or GND.
