‡
For I/O ports, the parameter I
OZ
includes the input leakage current.
§
This is the increase in supply current for each input that is at the specified TTL voltage level, rather than V
CC
or GND.
¶
This parameter specifies the dynamic power-supply current associated with the operating frequency of a single control input (see Figure 2).
#
Measured by the voltage drop between the A and B terminals at the indicated current through the switch. ON-state resistance is determined by
the lower of the voltages of the two (A or B) terminals.

The propagation delay is the calculated RC time constant of the typical ON-state resistance of the switch and the specified load capacitance,
when driven by an ideal voltage source (zero output impedance).
