(1) V_IN and I_IN refer to control inputs. V_I, V_O, I_I, and I_O refer to data pins.
(2) All typical values are at V_CC = 3.3 V (unless otherwise noted), T_A = 25°C.
(3) For I/O ports, the parameter I_OZ includes the input leakage current.
(4) This is the increase in supply current for each input that is at the specified TTL voltage level, rather than V_CC or GND.
(5) Measured by the voltage drop between 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.
