This current applies to the control inputs only and represent the current required to switch internal capacitance at the specified frequency. The I and Y inputs generate no significant AC or DC currents as they transition. This parameter is not tested, but is guaranteed by design.

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 0.25ns 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. 09-0120 3 PS7017H 06/11/09 PI5C3253 Dual 4:1 Mux/DeMux Bus Switch Test Circuit Switch Position Test Switch Disable LOW Closed Enable LOW Closed tPD Open Definitions: CL = Load Capacitance (includes jig and probe capacitance) RT = Termination resistance (should be equal to ZOUT of the pulse generator) Enable and Disable Timing Diagram Propagation Delay Diagram Disable Enable 3V 1.6V Control Input 1.5V Switch Output Normally Low 3V t PZH Output Normally High t PLH 3V Output 1.5V 0.3V Switch GND 1.5V V OH 1.5V 1.5V V OL t PLH 0V t PHL VOL t PZH 0.3V 1.5V 1.5V 0V 0V t PLZ t PZL 3V Same Phase Input Translation VOH 0V Opposite Phase Input Transistion t PHL 3V 1.5V 0V 1.
