(1)

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

(2)

All typical values are at VCC = 3.3 V (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)

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.
