(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) This parameter specifies the dynamic power-supply current associated with the operating frequency of a single control input (see
Figure 4).
(6) 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.

Continuous Junction Temperature, T_J (°C)
(1) See datasheet for absolute maximum and minimum recommended operating conditions.
(2) Silicon operating life design goal is 10 years at 105°C junction temperature (does not include package interconnect
life).
(3) Enhanced plastic product disclaimer applies.
