(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.

=25C.
[2] This is the increase in supply current for each input that is at the specified TTL voltage level rather than V
CC
or GND.
[3] Measured by the voltage drop between the nA and the nBn terminals at the indicated current through the switch. The lowest voltage of
the two (nA or nBn) terminals determines the ON resistance.
Table 5. Operating conditions
All unused control inputs of the device must be held at V
