Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2) All voltages are with respect to ground, unless otherwise specified.

(3) The input and output voltage ratings may be exceeded if the input and output clamp-current ratings are observed.

(4) V_I and V_O are used to denote specific conditions for V_I/O.

(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 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.

(2) Specified by design

(3) The bus switch contributes no propagational delay other than the RC delay of the on resistance of the switch and the load capacitance. The time constant for the switch alone is of the order of 0.25 ns for 10-pF load. Since this time constant is much smaller than the rise and fall times of typical driving signals, it adds very little propagational delay to the system. Propagational delay of the bus switch, when used in a system, is determined by the driving circuit on the driving side of the switch and its interactions with the load on the driven side.
