For Max. or Min.conditions, use appropriate value specifi ed under Electrical Characteristics for the applicable device.
Typical values are at V
Per TTL driven input (control input only); A and B pins do not contribute to I
This current applies to the control inputs only and represent the current required to switch internal capacitance at the specifi ed frequency. The
A and B inputs generate no signifi cant AC or DC currents as they transition. This parameter is not tested, but is guaranteed by design.
This parameter is guaranteed but not tested on Propagation Delays.
The bus switch contributes no propagational delay other than the RC delay of the On-Re sis tance of the switch and the load capacitance. The
time constant for the switch alone is of the order of 0.25ns for 50pF load. Since this time constant is much smaller than the rise/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 interaction with the load on the driven side.
