Notes: 1. VIN and IIN refer to control inputs. VI, VO, II, and IO refer to data pins.

2. All typical values are at VCC=3.3V (unless otherwise noted), TA=25°C.

3. For I/O ports, the parameter IOZ 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

VCC or GND.

5. This parameter specifies the dynamic power-supply current associated with the operating frequency of a

single control input.

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.

Notes: 1. Maximum switching frequency for control input (VO > VCC, VI = 5V, RL ≧ 1MΩ, CL = 0).

2. 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).
