Typical values are at V CC = 5.0V , TA = 25°C ambient and maximum loading. 3. Not more than one output should be shorted at one time. Duration of the test should not exceed one second. 4. Measured by the voltage drop between I and Y pin at indicated current through the switch. ON resistance is determined by the lower of the voltages on the two (I,Y) pins. Notes: 1.

Per TTL driven input (V IN = 3.4V , control inputs only); I and Y pins do not contribute to ICC. 4. This current applies to the control inputs only and represent the current required to switch internal capacitance at the spe ciﬁ ed frequency. The I and Y inputs generate no signiﬁ cant AC or DC currents as they transition. This parameter is not tested, but is guaranteed by design. Notes: 1. See test circuit and waveforms. 2. This parameter is guaranteed but not tested on Propagation Delays. 3. The bus switch contributes no propagational delay other than the RC delay of the On-Resistance of the switch and the load ca pacitance. 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.
