6. Functional description
[1] H = HIGH voltage level; L = LOW voltage level; Z = high-impedance OFF-state.
(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] Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under Section 8.

=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 nAn and the nBn terminals at the indicated current through the switch. ON resistance is
determined by the lowest voltage of the two (nAn or nBn) terminals.
10. Dynamic characteristics
[1] The propagation delay is the calculated RC time constant of the typical ON resistance of the switch and the specified load capacitance,
when driven by an ideal voltage source (zero output impedance).
